One-step electrochemical synthesis of Bi3.84W0.16O6.24 with superior photocatalytic activities

Bi3.84W0.16O6.24 nanoparticles were successfully prepared by a facile electrochemical route at room temperature in just 10 minutes. The phase composition, morphology and crystallinity can be well controlled by manipulating the volume ratio of ethanol–water in the solvent and the electric current value. The as-prepared products with relatively uniform size of 25 nm show superior visible light photocatalytic activities, which are even higher than that of nest-like Bi2WO6 particles with a larger specific surface area synthesized by a hydrothermal method.
