Description
Summary:Great interest has been attracted to enhancing the photoelectrochemical performances of BiVO 4 . 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 BiVO 4 , which may because it could improve the crystalline structure and eliminates the crystal defects of BiVO 4 . 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 BiVO 4 modified with MIL-53(Fe), which exhibits much higher PEC performance and stability than pristine BiVO 4 and Fe-doped BiVO 4 . It is believed that MIL-53(Fe) can capture the photogenerated holes and thus facilitates the charge separation efficiency. Graphical Abstract
