Defected ZnS/bulk g–C3N4 heterojunction with enhanced photocatalytic activity for dyes oxidation and Cr (Ⅵ) reduction

Defect–rich zinc sulfide (ZnS, ZS) was successfully synthesized by the slow release of S source from glutathione (GSH) to coordinate with Zn2+ at high temperature. Based on this, a novel ZnS/g–C3N4 (ZSCN) heterojunction with high catalytic activity was fabricated through facile in–situ hydrothermal method. The removal rates of Rhodamine B (RhB), methyl orange (MO), methylene blue (MB) and Cr6+ for ZSCN–0.05 with the highest catalytic activity...
