Abstract

Constructing noble-metal-free loaded catalyst with high-efficiency photocatalytic activity by a simple and scalable method is of profound significance for fundamental research and practical application.Herein,a simple one-pot method was used to synthesize novel samples of array-like sulfur-doped graphitic carbon nitride(SCN)nanosheets with ultrathin MoS2 loading(MS/SCN-x％).The ultrathin MoS2 cocatalyst was evenly distributed on the surface of SCN and was linked to the main catalyst by covalent chemical bonds.Benefited from the multiple advantages of the array-like porous nanosheets structure with rich exposed surface,covalent cross-linking structure,and enhanced visible light absorption,the MS/SCN-2.5％composites drastically improve hydrogen evolution performance,which is superior to orig-inal MoS2 nanosheet modified by two-step mixing method,and also rivals with Pt/SCN.The designing strategy of photocatalyst modified by noble-metal-free cocatalyst with covalent bond structure provides fascinating insights into enhanced photocatalytic hydrogen evolution.
