Silver decorated ZnO photocatalyst for effective removal of reactive red azo dye and ofloxacin antibiotic under solar light irradiation

Tammanoon Chankhanittha et al.

Summary: In this study, the incorporation of silver on ZnO photocatalyst significantly enhanced its visible-light-responsive performance and anti-photocorrosion property by creating a Schottky barrier at the silver/ZnO interface, leading to improved quantum efficiency and photocatalytic activity. Furthermore, the red shift in the absorption band towards the visible region due to the local surface plasmon resonance effect of the metallic silver also contributes to the enhanced photoactivity. The research findings suggest a novel approach for the fabrication of a promising silver-decorated ZnO photocatalyst for detoxification of organic pollutants in wastewater, showcasing excellent reusability and structural stability.
