Effect of Mixing Ratio and Doping Acid on the Photocatalytic Properties of PANI-BiVO₄ Composites

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.
