The BiVO4/WO3 heterojunction is the ideal photoanode for highly efficient solar water splitting. Despite much effort, the low light absorption efficiency near the BiVO4 band gap wavelength is still a major cause for loss of water-splitting efficiency. To address this issue, we introduce a heterojunction photoanode in which single crystal BiVO4 nanoparticles (NPs) are decorated on the WO3 surface. Such BiVO4 NPs enhanced the absorption efficiency. In addition, BiVO4 NPs exhibit high charge separation efficiency. As a result, the BiVO4 NP-coated WO3 photoanode achieves a remarkably high water splitting photocurrent. |
