Abstract Photocatalytically efficient ZnO:Ta/g-C3N4 coatings were deposited on stainless steel mesh (SSM) substrates using nebulizer spray technique for effective decomposition of toxic organic dyes discharged as textile effluents. Structure, morphology and composition of the coated material were analyzed using XRD, SEM and EDAX. Dye decomposition studies show that the efficiency increases remarkably when Ta and g-C3N4 are added with ZnO while the addition of Ta also results in moderate enhancement in efficiency. The reasons for this efficiency improvement and the underlying mechanism have been addressed in detail with the support of trapping test, XPS and UV-Vis diffuse reflectance spectroscopic studies.

通过 Ta+gC3N4 添加与 ZnO 的 O2- 增强和复合延迟有效的光催化染料分解

摘要 使用雾化器喷雾技术将光催化高效的 ZnO:Ta/g-C3N4 涂层沉积在不锈钢网 (SSM) 基材上，以有效分解作为纺织废水排放的有毒有机染料。使用XRD、SEM和EDAX分析涂层材料的结构、形貌和组成。染料分解研究表明，当 Ta 和 g-C3N4 与 ZnO 一起加入时，效率显着提高，而加入 Ta 也导致效率的适度提高。在捕获测试、XPS 和紫外-可见漫反射光谱研究的支持下，已经详细解决了这种效率提高的原因和潜在机制。
