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

Herein, we reported a octahedral Cd-3(C3N3S3)(2) coordination polymer as a new noble metal-free photocatalyst for robust photocatalytic H2O2 production from methanol/water solution. The coordination polymer can give an unprecedented H2O2 yield of ca. 110.0 mmol center dot L-1 center dot g(-1) at pH = 2.8 under visible light illumination. The characterization results clearly revealed that the photocatalytic H2O2 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(C3N3S3)(y) (M =transitional metals) coordination polymers as a series of new materials for solar energy storage and conversion.
