Abstract

Silver bromide/bismuth vanadate (AgBr/BiVO₄) composite was found to have excellent photosensitive properties. In comparison with bare BiVO₄ counterpart, the AgBr/BiVO₄ photoanode is more favorable to visible-light activation under AM1.5G illumination to achieve higher generation of electron-hole pairs. The AgBr/BiVO₄ composite can also retard recombination of the charges by means of heterojunction electron transport. As a result, the photogenerated electrons and holes have high reduction and oxidation capabilities, respectively. For the first time, AgBr/BiVO₄ photoanode was employed to construct a dual-photoelectrode photocatalytic fuel cell (PFC). The experimental analysis conducted revealed that the AgBr/BiVO₄ composite successfully enhanced the PFC to achieve excellent photoelectrochemical activities.
