Conventional wastewater treatment has been found to be less effective in removing various antiviral drugs and emerging pollutants from wastewater. As an advanced oxidation process, heterogeneous photocatalysis is promising to detoxify such water pollutants due to its mild operating conditions and efficiency. In this study, we explore the oxidative phase transition from bismuth iodide to bismuth oxyiodides

Graphitic Carbon nitride (g-CN) possesses properties that make it suitable for various applications, including photocatalysis, carbon dioxide reduction, sensing, water-splitting, and nitrogen fixation. To overcome performance limitations arising from limited visible-light absorption and rapid recombination of photo-induced charge carriers, we employ heteroatom doping in a minimally impactful manner

The presence of submicron- (1 µm – 100 nm) and nanoplastic (< 100 nm) particles within various sample matrices, ranging from marine environments to foods and beverages, has become a topic of increasing interest in recent years. Despite this interest, very few analytical techniques remain that allow for the detection of these small plastic particles in the low concentration ranges that they are anticipated

Black phosphorus (BP) nanomaterials are promising for biomedical applications owing to their extraordinary biodegradability. Although previous research has demonstrated changes in the physicochemical properties of BP due to degradation, the impact of degradation on BP interactions with biological systems remains unclear. In this study, we designed a set of BP nanomaterials with varying degrees of degradation

Nanoplastics (NPs) in the environment have attracted attention worldwide as a new class of pollutant. However, their impacts on aquatic organisms are only beginning to be unraveled. The current study investigated the toxic effects and mechanisms of action of polystyrene NPs (PS-NPs) on liver apoptosis and the intestinal histological structure and flora of the economically important eel Monopterus albus

While the use of engineered nanomaterials (ENMs) is expanding to various applications and commercial products, public concerns are raising on their potential hazards to the exposed humans. Dermal absorption is the principal entry route for ENMs derived from various consumer products whose direct contacts with skin are often inevitable. Rapid nanosafety assessment of ENMs at their early development

Wildfire causes detrimental problems to animals and plants. Nanoparticles with enzymatic activities were applied to repair the damage caused by fire and potentially degrade the produced pollutants. Kinetic studies revealed for the first time an allosteric mechanism of the nanozyme. The present work aims to reveal the advantage offered by the phosphatase-like (PL) nanozyme formed by baking L-cysteine

Microplastics pollution has aroused considerable attentions. Here, we develop a visible-light-driven photocatalysis and photothermal Fenton-like reaction method for their removal, utilizing α-Fe2O3 nanoflower on TiO2 with a hierarchical structure of inverse opal-like layer/nanotube arrays (α-Fe2O3/TiO2HNTAs film). Without external H2O2 dosage, nearly 100% degradation of 310 nm polystyrene (PS) sphere

Organic ammonium salts which are formed from heterogeneous reactions are one of the important components of Nitrogen-containing organic compounds (NOCs) in atmosphere. In order to investigate the formation process of organic ammonium salts, a gas-flow system with Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) technique was applied to monitor the influence of simulated illumination
