Impact of Heterovalent Cu²⁺ and Ag⁺ Doping on the Structural, Optoelectronic, and Photocatalytic Properties of ZnO for Enhanced Solar-Driven Hydrogen Evolution and Organic Pollutant Degradation.

ABSTRACT: The preparation of photocatalysts capable of harnessing solar light energy as a sustainable and renewable source for treating wastewater containing organic pollutants and for H₂ production from water splitting represents a significant direction in the photocatalyst field. In this study, S-scheme CuO/Ag₂O-ZnO heterostructures with different CuO contents were prepared by the sol-gel method. XRD results confirmed the doping of ZnO by Ag⁺ and Cu²⁺. Also, the intensity of peaks decreased obviously after the addition of Ag⁺, while the addition of Cu²⁺ was accompanied by an increase in the peak intensity. UV-visible analysis results displayed a significant red shift of the absorption edge to the visible region, and a remarkable red
