A novel composite is constructed by loading ZIF-8 on Cu2O by in situ growth. By visible light driven semiconductorand p-p* conjugation effect of the metal–organic framework, the migration ability of photogeneratedcarriers is improved, and electrons are accumulated to participate in hydrogen ionreduction. The superior hydrogen evolution performance (981.8 lmolg1h1) and stability test indicatethat the coupling of ZIF-8 and semiconductor Cu2O successfully improves the catalytic capacity of thematerial. Cu2O provides a place to stimulate activity for ZIF-8 with high specific surface area. The electrontransfer mechanism in composites is studied by electrochemical and spectroscopy methods. This workalso provides a new opportunity for the in-situ growth of metal–organic frame materials onto singlemetaloxides.
