Highly efficient nitrogen fixation over S-scheme heterojunction photocatalysts with enhanced active hydrogen supply.

ABSTRACT: Photocatalytic N₂ fixation is a promising strategy for ammonia (NH₃) synthesis; however, it suffers from relatively low ammonia yield due to the difficulty in the design of photocatalysts with both high charge transfer efficiency and desirable N₂ adsorption/activation capability. Herein, an S-scheme CoS_x/ZnS heterojunction with dual active sites is designed as an efficient N₂ fixation photocatalyst. The CoS_x/ZnS heterojunction exhibits a unique pocket-like nanostructure with small ZnS nanocrystals adhered on a single-hole CoS_x hollow dodecahedron. Within the heterojunction, the electronic interaction between ZnS and CoS_x creates electron-deficient Zn sites with enhanced N₂ chemisorption and e
