Bimetallic Fe/Ni-based metal-organic frameworks(MOFs)with different Fe/Ni ratios were coated on TiO_(2)nanorods(NRs),and the performances of the heterojunction photoanodes in photoelectrochemical water splitting were *** bandgaps and band positions of the MOFs could be modulated by changing the ratio of the Fe and Ni *** ideal band alignment was achieved between the TiO_(2)NRs and bimetallic MOFs with an optimum ratio of[Fe]/[Ni]=0.25/0.75,which allowed efficient light absorption and charge *** coating of NH_(2)-MIL(Fe)-88 layer on the TiO_(2)NRs decreased the photocurrent density by 33%.In comparison,TiO_(2)/NH_(2)-MIL(Ni)-88 showed a modest improvement in photocurrent density(0.85 mA·cm^(−2)at 1.23 V vs.a reversible hydrogen electrode(RHE)).When bimetallic NH_(2)-MIL(Fe_(0.25)Ni_(0.75))-88 was coated on the TiO_(2)NRs,the photocurrent density reached 1.56 mA·cm^(−2),which was an efficiency enhancement of 3.2 *** mechanism underlying high photoelectrochemical performance was investigated.
