Abstract The exceptional performance of graphdiyne (GDY) in photocatalysis for hydrogen evolution attracts much attention, but the narrow band gap GDY complicates effective realization dissociation between photogenerated charges and holes. In this study, GDY‐CuI is synthesized by cross‐coupling method, wide bandgap ZnWO 4 introduced into it low‐temperature mixing, which effectively constructed GDY‐CuI/ZW‐50 double S‐scheme heterojunction. optimized catalyst photocatalytic reached 308.61 µmol after 5 h visible light irradiation, 12.86 6.56 times than that , respectively. improved efficiency attributed to formation a heterojunction GDY, CuI, an internal electric field, promotes charge transfer, reduces complexation rate electrons, enhances redox capacity charges. A combination photoelectrochemical analysis, situ X‐ray photoelectron spectroscopy (In XPS), ultraviolet (UPS), density functional theory (DFT) results revealed electron transfer mechanism. This work will provide new ideas design preparation GDY‐based photocatalysts.
