Abstract：

It　is　of　great　interest　to　enhance　the　photoelectrochemical　hydrogen　production　rate　of　TiO2　by　utilizing　the　new　Metal-organic　frameworks　material　such　as　NH2-MIL-125(Ti),　but　the　assembly　method　and　its　details　often　bring　about　a　significant　difference　in　performances　of　the　composite　photoelectrode.　In　this　study,　NH2-MIL-125　is　grown　on　the　surface　of　TiO2　nanorods　by　an　in-situ　strategy,　and　then　Cu-modified　NH2-MIL-125/TiO2　photoanode　is　prepared　by　impregnation　method.　Based　on　the　characterization　of　SEM,　UV-VIS　DRS　and　PL　spectra,　the　disc-like　NH2-MIL-125　can　improve　the　light　absorptance　in　visible　light　region,　and　the　modification　of　Cu+/Cu2+　can　inhibit　the　charge　recombination　in　NH2-MIL-125/TiO2　photoanode,　resulting　in　the　improved　the　carrier　transport　ability　verified　by　EIS　and　IMPS.　Under　AM　1.5　illumination,　H2　evolution　rate　over　Cu-NH2-MIL-125/TiO2　is　boosted　a　great　extent,　which　is　4.6　times　than　that　of　pristine　TiO2.　©　2023　Hydrogen　Energy　Publications　LLC
