Electronic Structure Modulation of Bimetallic Sulfides for Efficient Sacrificial-Agent-Free Photocatalytic H2 Evolution

The consumption of sacrificial agents is inevitable to improve the separation and utilization of electron–hole pairs in photocatalytic H2 evolution, which is contrary to the current vision of carbon neutrality and carbon peak. Here, bimetallic sulfides composed of highly dispersed Cu-doped ZnS composites were proposed, exhibiting an optimal H2 evolution activity of over 1569 μmol/g at 2 h (0.5 g/L catalyst) under visible light irradiation at pH …
