Here we report a visible light photocatalyst RGO–Ag/AgCl composite, prepared in a simple protocol. The photocatalytic activity of RGO–Ag/AgCl is demonstrated with an in-house developed white light emitting diode reactor. RGO–Ag/AgCl is characterized by FESEM, PXRD, EDX, FTIR, and UV–visible spectroscopy. RGO–Ag/AgCl has strong absorbance in the visible light region and exhibits enhanced photocatalytic activity compared to Ag/AgCl for the photodegradation of RhB. Only a minimal change in the photocatalytic activity of RGO–Ag/AgCl is observed in repeated cycles. The photodegradation pathway followed is of a dominant direct degradation of the chromophore rather than the commonly observed N-deethylation pathway. Thus reducing the chances of leftover photodegradation products as contaminants. Our findings suggest that RGO–Ag/AgCl under visible light from WLED has the potential to be used for water treatment.

在这里，我们报告了一种通过简单协议制备的可见光光催化剂RGO-Ag / AgCl复合材料。内部开发的白色发光二极管反应器证明了RGO-Ag / AgCl的光催化活性。RGO–Ag / AgCl的特征在于FESEM，PXRD，EDX，FTIR和UV可见光谱。与Ag / AgCl相比，RGO-Ag / AgCl在可见光区域具有很强的吸收性，并且对RhB的光降解表现出增强的光催化活性。在重复循环中，仅观察到RGO-Ag / AgCl的光催化活性有最小的变化。遵循的光降解途径主要是生色团直接降解，而不是通常观察到的N-脱乙基途径。因此减少了剩余的光降解产物作为污染物的机会。
