The significance of enhanced photocatalytic degradation of RhB on the synthesis, characterization, and effects of Ag doped CdS-WO2 Nano composites

Abstract

A simple and sealing agent-free hydrothermal approach was used to fabricate the very modest Ag/CdSWO2 Nano composite in this article. Powder X-ray diffraction (XRD) and UV-vis diffuse reflectance (DRS) spectroscopy was used to characterise the synthesized Ag loaded CdS-WO2 Nano composite. Under visible light irradiation (VLI), the photocatalytic activity of synthesized photocatalysts was tested for the photodegradation of rhodamine B (RhB). pH, catalyst dose, oxidant dose, and irradiation time were the parameters employed to optimise the photocatalyst. A plausible reaction mechanism for improving Ag/CdS-WO2 photocatalytic activity has been postulated based on this. As a result, we have an inclination to assume that it could be a promising material for photodegradation of organic contaminants in wastewater.
