Abstract

Great interest has been attracted to enhancing the photoelectrochemical performances of BiVO4. However, there have rarely been reported about addressing their PEC stability. Herein, it is proposed that Fe ions doping could enhance the stability and PEC performances of BiVO4, which may because it could improve the crystalline structure and eliminates the crystal defects of BiVO4. Moreover, it is found that metal–organic framework can play a co-catalyst role during the PEC experiments. We designed and fabricated nanoporous Fe-doped BiVO4 modified with MIL-53(Fe), which exhibits much higher PEC performance and stability than pristine BiVO4 and Fe-doped BiVO4. It is believed that MIL-53(Fe) can capture the photogenerated holes and thus facilitates the charge separation efficiency.
