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

摘要

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.
