Abstract

BiVO4 photocatalyst prepared by hydrothermal method was mixed with polyaniline (PANI). The phase structure, morphology and optical properties of PANI-BiVO4 photocatalysts were analyzed through X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis diffuse reflectance spectroscopy (DRS). The results showed that the optimal preparation conditions of composite photocatalyst were 0.5wt.% PANI mixing ratio and H3PO4 as doping acid. The photocatalysis degradation rate is the highest. This new heterogeneous structure photocatalyst is expected to show considerably potential applications in solar-driven environmental pollution cleanup.
