Abstract

Abstract: ZnO/SnO2 nano-composites with different compositions were synthesized by co-precipitation method and further characterized by XRD and TEM. Synthesized photocatalysts were employed for the degradation of a persistent pesticide, Triclopyr (TC). Triclopyr is a well-known herbicide and fungicide. Coupled ZnO/SnO2 photocatalysts showed better degradation of TC than the pure ZnO or SnO2 . The nanocomposite containing the 10% of SnO2 content (ZS-2) exhibited highest photo catalytic activity towards degradation of TC. Higher activity of the coupled oxides is attributed to the reduced recombination of photogenerated charged species due to formation of hetro-junctions between ZnO/SnO2 .
