Abstract

Abstract: In this work, BiVO₄ powders were synthesized by a sol-gel method, and the BiVO₄ gels with different calcination temperaturewere investigated by X-ray diffraction (XRD). Absorption range and band gap energy,which are responsible for the observed photocatalyst behavior,were investigated by UV/vis diffuse reflectance spectroscopy (DRS) for pure and silver oxide loaded BiVO₄. Photocatalytic properties of the prepared samples were examined by studying the degradation of themethyl orange. When using NaClO₂ as an electron acceptor, the possible photocatalytic mechanism has been discussed by photocatalytic reactions.With the help of electron acceptor, the results show clearly that the BiVO₄ loaded silver oxide exhibited superior photocatalytic activity in simulated dye wastewater treatment.
