Single-atom catalyst technology with near-100% atomic utilization and a well-defined coordination structure has provided new ideas for designing high-performance photocatalysts, which is also beneficial reducing the usage of noble metal cocatalysts. Herein, series single-atomic MoS2-based cocatalysts where monoatomic Ru, Co, or Ni modify MoS2 (SA-MoS2) enhancing photocatalytic hydrogen production performance g-C3N4 nanosheets (NSs) are rationally designed synthesized. The 2D SA-MoS2/g-C3N4 photocatalysts single atoms show similar enhanced activity, optimized Ru1–MoS2/g-C3N4 photocatalyst highest rate 11115 μmol/h/g, about 37 5 times higher than that pure MoS2/g-C3N4 respectively. Experimental density functional theory calculation results reveal mainly attributed to synergistic effect intimate interface between SA-MoS2 structures NSs, conducive rapid interfacial charge transport, unique modified electronic appropriate adsorption offers abundant reactive sites performance. This work provides insight into improving cocatalytic by strategy.
