Abstract

BiVO ₄powders with unique particle architectures have been synthesized using ultrasonic spray pyrolysis (USP). Gases created from the evaporation of solvent and the decomposition of precursor materials shape the morphology of the particles as the solids are formed in the heated aerosol. The BiVO4powder was tested as oxygen evolving photocatalysts by monitoring the kinetics of O ₂formation from a AgNO ₃solution irradiated with λ > 400 nm light. USP prepared BiVO ₄was found to have significantly superior photocatalytic activity compared to commercial BiVO ₄and WO ₄, likely due to differences in particle morphology.
