Robust Photocatalytic H2O2 Production by Octahedral Cd3(C3N3S3)2 Coordination Polymer under Visible Light

Abstract Herein, we reported a octahedral Cd 3 (C 3 N 3 S 3 ) 2 coordination polymer as a new noble metal-free photocatalyst for robust photocatalytic H 2 O 2 production from methanol/water solution. The coordination polymer can give an unprecedented H 2 O 2 yield of ca. 110.0 mmol • L −1 • g −1 at pH = 2.8 under visible light illumination. The characterization results clearly revealed that the photocatalytic H 2 O 2 production proceeds by a pathway of two-electron reduction of O 2 on the catalyst surface. This work showed the potential perspective of M x (C 3 N 3 S 3 ) y (M = transitional metals) coordination polymers as a series of new materials for solar energy storage and conversion.
