摘要：

BiVO4/WO3heterojunction film is considered as a very promising candidate for photoelectrochemical water splitting. However, the BiVO4/WO3films prepared by a conventional method exhibit numerous grain boundaries in the BiVO4layer and a weak contact at the heterojunction interface. In this paper, we found that BiVO4could be formed from hydrothermal Bi2WO6in the weak acid solution dissolving V2O5and successfully developed an in situ transformation method to prepare BiVO4/WO3heterojunction films. The prepared BiVO4/WO3heterojunction films were characterized in detail and showed a high quality core...
