Glucose from plants or food industry wastes is a cost-effective hole scavenger for photocatalytic water splitting, but the related H2 evolution rate always restricted by fast recombination of photo electron-hole pairs and poor intrinsic activity traditional Pt cocatalysts. Herein, we fabricated Au-Pt heterostructure cocatalyst that consist one ∼3 nm Au core several ∼1 islands on ultrathin g-C3N4 through one-pot photo-deposition. The exhibited superior to monometallic nanoparticles. Our experiments theoretical calculations demonstrated enhanced was caused synergistic effect between Pt, rather than well-known plasmonic Au. not only favored trapping electrons g-C3N4, also had suitable adsorption strength H*, exhibiting high towards evolution. research provides strategy boost regulating synergy bimetallic
