Abstract

To the best of our knowledge there are no research in the literature on the catalytic hydrogen peroxide (H₂O₂) decomposition utilizing the pure Bi₁₂SiO₂₀ (BS) and transition metal ions doped Bi₁₂SiO₂₀ (M/BS; M = Fe, Cu, Ni, Co or Mn) as catalysts. The effect of transition metal ions doping on the crystal structure, morphology, surface and porous properties of Bi₁₂SiO₂₀ nanomaterial was estimated by the XRD, TEM and BET analysis. Interestingly, the doped nanomaterials possessed bigger specific surface areas and larger pore volumes than that of pure BS nanomaterial. Noteworthy, the catalytic performance of Bi₁₂SiO₂₀ catalyst was gradually promoted in the existence of the different transition metal ions as dopants. Interestingly, the performance of Bi₁₂SiO₂₀ catalyst was remarkably promoted with NiO, Co₃O₄ and Mn₃O₄ doping by conversion about 38.1% 41.9% and 71.4%, respectively. Furthermore, the H₂O₂ decomposition conversion was found to be 71.4, 82.9 and 90.5% on the most active catalyst (Mn/BS) at 20 °C, 35 °C and 50 °C, respectively. Finally, the Mn/BS catalyst demonstrated larger stability in the H₂O₂ decomposition and can be recycled several times.

Introduction

Hydrogen peroxide (H₂O₂) is an environmentally friendly oxidant and significant goods chemical as its only decomposition by-product is water [1]. The catalytic decomposition of H₂O₂ is considerably examined because of its applicability in several industrial and environmental technologies, the performance of those technologies being powerfully related with the H₂O₂ decomposition [2], [3], [4]. Consequently, it is widely applied in wastewater treatment using NAS approach based on algae-bacteria consortia CO₂ and NO_x removal [5,6], pulp industry and as a raw material in chemical industry [1,7,8]. Additionally, H₂O₂ is used commonly as an antimicrobial agent in food processing, a bleaching agent of natural and synthetic fibers in textile industry and in pharmaceutical applications [9,10]. Moreover, H₂O₂ decomposition is applied as a probe reaction for redox catalytic efficiency of metal oxides [1] since long time. On account of the activity of H₂O₂ decomposition is very weak, it commonly carries out in the existence of catalysts [11,12]. Recently, nanomaterials have attracted considerable interest of the scientific and industrial communities owing to their remarkable physical properties, opening chances for a very wide diversity of new technological applications [13]. Amongst, bismuth silicate (Bi₁₂SiO₂₀), which belongs to the sillenite type with a pseudo-body centered cubic unit cell and I23 space group symmetry [14,15]. Bi₁₂SiO₂₀ is a multifunctional substance with fascinating optical and physicochemical properties [16]. So, it has good photocatalytic [17], [18], [19], photochromic, photorefractive and dielectric properties [15,19]. Additionally, different dopants were investigated to promote the optical and physicochemical properties of Bi₁₂SiO₂₀ [18]. Transition metal oxides as dopants were attracted a great interest of the researchers [[20], [21], [22]] owing to their low cost, availability, and high efficiency [23]. Among different transition metal oxides, cobalt (Co₃O₄) and manganese (Mn₃O₄) oxides, which belong to the spinel class of minerals with molecular formula of M²⁺‏(M^3‏(⁺₂(O²⁻)₄ [24,25]. Additionally, Co₃O₄ and Mn₃O₄ were attracted attention due to their promising applications such as active catalysts in many redox reactions, gas sensors and anodic materials in lithium-ion batteries [20,22,26,27]. Also, amongst them, iron oxide (Fe₂O₃) which attracted much notice for H₂O₂ decomposition owing to comparatively low cost, non-toxicity, good stability and environmentally friendly feature [28,29]. Moreover, Fe₂O₃ nanomaterials used in several applications like wastewater treatment, gas sensor materials, lithium batteries, supercapacitors, catalysts and non-enzymatic glucose sensors [30], [31], [32]. Besides, copper (CuO) and nickel (NiO) oxides obtained growing interest not only for their distinctive properties but also for their different applications in catalysis, gas sensors and magnetic materials [[33], [34], [35], [36], [37], [38]].

To the best of our knowledge there are no reports on the H₂O₂ decomposition utilizing pure or doped Bi₁₂SiO₂₀ as catalyst. Therefore, it was thought of attention to study the catalytic activity of pure Bi₁₂SiO₂₀ (BS) and transition metal ions doped Bi₁₂SiO₂₀ (M/BS; M = Fe, Cu, Ni, Co or Mn) in H₂O₂ decomposition. Pure and doped Bi₁₂SiO₂₀ nanomaterials were successfully prepared by ultrasonic-assisted hydrothermal route. The effect of transition metal ions doping on the physicochemical properties of Bi₁₂SiO₂₀ nanomaterial was estimated by X-ray diffraction (XRD), transmission electron microscopy (TEM) and nitrogen adsorption-desorption analysis. In the end, the stability of catalyst was investigated by recycling experiment for five sequential runs.

Conclusions

Interestingly, the catalytic performance of Bi₁₂SiO₂₀ catalyst was remarkably promoted with NiO, Co₃O₄ and Mn₃O₄ doping.

Recent advances in designing and developing efficient sillenite-based materials for photocatalytic applications
2024, Advances in Colloid and Interface Science
Sillenite materials have been the subject of intense investigation for recent years due to their unique characteristics. They possess a distinct structure with space group I23, allowing them to exhibit distinctive features, such as an electronic structure ideal for certain applications such as photocatalysis. The present research delves into the structure, synthesis, and properties of sillenites, highlighting their suitability for photocatalysis. It explores also advanced engineering strategies for designing sillenite-based photocatalysts, including heterojunction formation, morphology modification, doping, and hybrid processes. Each strategy offers advantages and limitations that are critically discussed. The review then lists and discusses the photocatalytic performance of various sillenite-based systems recently developed for common applications, such as removing hazardous organic and inorganic contaminants, and even infrequent applications, such as microbial inactivation, H₂ generation, CO₂ reduction and N₂ fixation. Finally, valuable insights and suggestions are put forward for future research directions in the field of sillenite-based photocatalysis. This comprehensive overview would provide a valuable resource for the development of efficient photocatalytic systems to address environmental and energy challenges.
Multicomponent metal nanoparticles supported on nickel foam for efficient catalytic decomposition of vaporized hydrogen peroxide
2024, Journal of Environmental Chemical Engineering
Residual high-concentration vaporized hydrogen peroxide (VHP) after disinfection poses a significant threat to human health and the disinfection space. The considerable concerns make it necessary to develop efficient catalysts for VHP decomposition. In this work, three-dimensional (3D) porous Ni foam (NF)-based multicomponent nanocomposites were fabricated via a facile in-situ hydrothermal method. The effect of the composition and content of elements on the catalytic decomposition of VHP was studied. The AlCrFePt_0.64/NF catalyst exhibits the best catalytic performance among all catalysts and requires only 59 min to reduce the VHP concentration from 250 ppm to 1 ppm. Furthermore, the AlCrFePt_0.64/NF shows superior stability and no obvious change in VHP decomposition performance after ten recycling tests. The decomposition of VHP follows a pseudo-first-order kinetics rate law. The catalytic decomposition mechanism of VHP proceeds through O-O splitting and consecutive H-transfer reactions. The enhanced catalytic activity of the AlCrFePt_0.64/NF is ascribed to the synergetic effect of noble-metal Pt and transition metals, which leads to the presence of initially larger amounts of surface O* and HO* species, and lower activation energy of the O-O bond splitting.
Facilely prepared heterogeneous Fenton catalyst Fe(Fe<inf>0.69</inf>Al<inf>0.31</inf>)<inf>2</inf>O<inf>4</inf>@C for catalytic wet peroxide oxidation of ciprofloxacin in batch and continuous reactor: Reaction intermediates and toxicity evaluation
2024, Separation and Purification Technology
Herein, by using a simple co-precipitation method Al-doped magnetite spinel nanoparticle encapsulated in the carbon matrix Fe(Fe_0.69Al_0.31)₂O₄@C was synthesised and its catalytic activity was examined as a heterogeneous Fenton catalyst towards the catalytic wet peroxide oxidation (CWPO) of antibiotic pollutant 20 ppm ciprofloxacin (CIP) in batch and continuous reactors. Under the optimized conditions, 0.5 g·L^-1 Fe(Fe_0.69Al_0.31)₂O₄@C in batch reactor mineralized 51 % of CIP was achieved within 180 min at 50 °C and pH 3 by utilizing 1.2 mM or 4S H₂O₂ (S = stoichiometry; 47 mol H₂O₂:1 mol CIP) which is significantly less concentration compared to other heterogeneous Fenton catalysts. Impressive long-lasting catalytic activity was demonstrated in the up-flow fixed bed reactor, for 110 h with 44 % TOC removal and less than 1 ppm Fe leaching in the effluent water. Kinetic studies on the rate of decomposition of H₂O₂ revealed that Fe(Fe_0.69Al_0.31)₂O₄@C effectively decomposed the H₂O₂ like the homogeneous Fenton catalyst. The XPS results confirmed the influence of Al on iron ions in the magnetite structure through a substantial shift in higher binding energy for Fe³⁺ and introduced a more electropositive character on the Fe^3+(δ+) that successively expedites the kinetically slow Fe³⁺ reduction reaction with H₂O₂ to produce HOO^•. The π electrons of the graphitic carbon facilitate the electron transfer between the carbon matrix and Fe(Fe_0.69Al_0.31)₂O₄ nanoparticles to enhance the CIP degradation. The acute toxicity assessment studies validated the non-toxic nature of the effluent water obtained from batch and continuous reactors. A degradation pathway was proposed based on the eleven intermediate products identified using LC-HRMS analysis.
Study on the interaction of anions and cations in the synthesis of nanoflower bismuth silicate and its photocatalytic removal of dyes and antibiotics
2023, Journal of Alloys and Compounds
It is challenging to construct photocatalysts with excellent adsorption-photocatalytic synergy and multi-system pollutant degradation by utilizing double heterostructure with unique nanoflower structure and energy band modulation. Here, a nanoflower-like double-heterojunction composite photocatalyst with high visible light activity is prepared in situ by ion exchange, namely BOSBM (M=I, B, C, K, L; the modified ions are I^-, Br^-, Cl^-, K^- and Li^-). On the other hand, surface-charged ions provide multiple adsorption sites for pollutants. In BOSBC-6 (the ion is Cl^-, the concentration is 1.05 mol/L) photocatalyst, the photocatalytic performance (10 min, degradation rate of 98 %) is 4 times that of BOS. It still has excellent catalytic stability (30 min, 98 % degradation rate) even after 3 cycles of testing. Meanwhile, BOSBM exhibited high degradation efficiency for dye (RhB) and various antibiotics (norfloxacin, ciprofloxacin, and tetracycline hydrochloride). Due to its upward shifting structure (Vo level), BOSBM plays an important role in the degradation of multi-system pollutants. In particular, the formation of Bi₂O₂SiO₃-BiOCl and Si₂Bi₂₄O₄₀-BiOCl double heterojunctions in BOSBC-6, which significantly improves the separation efficiency and increases the redox capacity of the sample. Therefore, this work broadens the application range of bismuth silicate photocatalysts and provides a new strategy for obtaining photocatalysts with excellent adsorption-photocatalytic synergistic effect by utilizing the heterojunction structure for modification purposes.
Jointly augmented photocatalytic NO removal by S-scheme Bi<inf>12</inf>SiO<inf>20</inf>/Ag<inf>2</inf>MoO<inf>4</inf> heterojunctions with surface oxygen vacancies
2023, Journal of Colloid and Interface Science
The deep oxidation of NO molecules to NO₃^– species with the avoidance of toxic NO₂ generation is a big and challengeable concern, which can be solved by the rational design and construction of catalytic systems with satisfactory structural and optical features. For such, in this investigation binary composites Bi₁₂SiO₂₀/Ag₂MoO₄ (BSO-XAM) were fabricated through a facile mechanical ball-milling route. From microstructural and morphological analyses, heterojunction structures with surface oxygen vacancies (OVs) were simultaneously created, contributing to the enhanced visible-light absorption, reinforced migration and separation of charge carries, and further boosted generation of reactive species such as superoxide radicals and singlet oxygen. Based on the density-functional theory (DFT) calculations, surface OVs induced the strengthened adsorption and activation of O₂, H₂O, and NO molecules and oxidation of NO to NO₂, while heterojunction structures were beneficial for the continuous oxidation of NO₂ to NO₃^– species. Thus, the heterojunction structures with surface OVs synergistically guaranteed the augmented photocatalytic NO removal and constrained NO₂ generation of BSO-XAM through a typical S-scheme model. This study may provide scientific guidances for the photocatalytic control and removal of NO at ppb level by Bi₁₂SiO₂₀-based composites through the mechanical ball-milling protocol.
Externally modified Bi<inf>12</inf>SiO<inf>20</inf> with BiOI: n-p heterojunctions for effectually photocatalytic degradation of bisphenol A
2023, Separation and Purification Technology
The effectual removal of bisphenol A (BPA) molecules is of great significance considering the hazards to the environment and human health. For such, externally BiOI-decorated Bi₁₂SiO₂₀ (BSI) composites were successfully fabricated via a facile post-synthesis protocol and systematically characterized by various analytical techniques. Both expected components were identified and combined tightly in composites to generate n-p heterojunction structures. Under the visible light, these n-p heterojunction composites BSI provided the significantly improved photocatalytic removal abilities of colorless BPA. Particularly, the best candidate BSI-60 owned the largest apparent reaction rate constant (K_app) 32.72 × 10⁻³ min⁻¹ that were 48.8 and 2.04 times of those Bi₁₂SiO₂₀ and mixture BSI 60, mainly attributing to the enlarged specific surface area (S_BET), strengthened visible light harvesting, and boosted charge carriers separation and further active species generation by heterojunction structures with the suitable phase composition. These composites possessed favorable reusability and structural stability and followed a typical type-II mechanism in the light of entrapping experimental and analytical results. This study may provide a research guidance for the creation of Bi₁₂SiO₂₀-based composites for effectual BPA removal through photocatalytic processes under visible light.
