Development of a novel and high performance visible‐light‐induced Cd₃OSO₄ nanophotocatalyst for degradation of diazinon

Abstract

One of the most important challenge in recent years is the removal and even better than that the degradation of poisons from environmental systems. Nanostructures due to their interesting properties are very suitable for this purpose. Herein, Cd3OSO4 nanomaterial was synthesized with a simple co precipitation method, characterized and was used, as a visible‐light‐driven photocatalyst in degradation of diazinon. The experimental conditions were also optimized. The results showed degradation efficiency is about 90%. Moreover, some kinetic studies were performed and showed this system obeys first order kinetics. Photo‐ oxidation mechanism was investigated in the presence of hole and electron scavengers. This is the first report on the investigation of the photocatalytic properties of Cd3OSO4 nanomaterial. The calculations of band gap of this new photocatalyst (1.85ev) showed its capability for application as a new visible light driven photocatlyst.
