Textile dye industry is known to release large amounts of undesirable effluents into industrial wastewater resulting in severe contamination. In this study, novel nanostructured materials were synthesized to treat such polluted water. Transition metals (e.g., vanadium—V, niobium—Nb, and tantalum—Ta) were incorporated individually into tellurium (Te) by adopting the solid-state technique. The compounds were synthesized with fixed dopant-to-host stoichiometric ratios (V:Te, Nb:Te, Ta:Te) while various characterization techniques were used to compare the characteristics of the synthesized products. Specifically, dye aqueous solution degraded with NaBH₄ in the presence of tellurites of transition metal oxides acting as catalyst was studied. XRD analysis confirmed the formation of orthorhombic phase compounds in V and Ta and monoclinic compounds within Nb. Full-width at half-maximum (FWHM) data were extracted from the most intense peak in the XRD spectrum to measure the crystallite size using the Debye–Scherrer method. FESEM was used to investigate the surface morphology of the prepared compounds, which showed agglomerated particles that possessed an irregular shape. HR-TEM was employed to gain a detailed insight into the material’s crystal structure. Optical properties, functional group and chemical composition were recorded using UV–Vis, FTIR spectroscopy and EDS analysis, respectively. Raman spectroscopy was carried out to confirm the stretching vibrations and modes of the synthesized products. Thermal stability of the compounds was confirmed at high temperature with DSC/TGA. Moreover, the antimicrobial activity of these binary systems was tested against Escherichia coli (gram-ive) and Staphylococcus aureus (gram + ive) bacterial strains. It was observed that bactericidal potential was the highest at maximum concentrations of the dopant.

众所周知，纺织染料工业会将大量不良废水排放到工业废水中，从而导致严重污染。在这项研究中，合成了新型纳米结构材料来处理这种污水。通过采用固态技术，将过渡金属（例如钒-V，铌-Nb和钽-Ta）单独掺入碲（Te）中。以固定的掺杂剂与主体的化学计量比（V：Te，Nb：Te，Ta：Te）合成化合物，同时使用各种表征技术比较合成产物的特性。具体而言，用NaBH ₄降解的染料水溶液研究了在碲酸盐存在下过渡金属氧化物作为催化剂的存在。XRD分析证实在V和Ta中形成正交相化合物，在Nb中形成单斜晶化合物。使用Debye-Scherrer方法从XRD光谱中最强的峰中提取半峰全宽（FWHM）数据，以测量微晶尺寸。FESEM被用来研究所制备化合物的表面形态，显示出具有不规则形状的附聚颗粒。使用HR-TEM可以深入了解材料的晶体结构。分别使用UV-Vis，FTIR光谱和EDS分析记录光学性质，官能团和化学成分。进行拉曼光谱确认合成产物的拉伸振动和模式。使用DSC / TGA在高温下确认了化合物的热稳定性。此外，还对这些二元系统的抗微生物活性进行了测试。大肠杆菌（革兰氏阳性）和金黄色葡萄球菌（革兰氏阳性）细菌菌株。观察到最大浓度的掺杂剂具有最高的杀菌潜能。
