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

Abstract

Herein, we reported a octahedral Cd3(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 • L−1 • 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 O2 on the catalyst surface. This work showed the potential perspective of Mx(C3N3S3)y (M = transitional metals) coordination polymers as a series of new materials for solar energy storage and conversion.

Synthesis of Metal–Organic Sulfides as Anode Materials for Lithium‐Ion Batteries at Room Temperature

“…The monomer of the macromolecule is M 3 (TMT) 2 , and the divalent metal ions could be Ni 2+ , Co 2+ , Mn 2+ , Zn 2+ , Cd 2+ , Hg 2+ , Pb 2+ , Cu 2+ , Sn 2+ , etc . Divalent metal ions form coordinate bonds with two sulfur ions; at the same time, the metal ions also coordinate with the adjacent nitrogen atoms …”

Phosphorylation of g-C3N4 for enhanced photocatalytic CO2 reduction

“…At present, artificial photocatalysts usually were inorganic semiconductor such as oxides and sulfides, which were very different from the enzymes in plant tissues. Therefore, more and more biomimetic photocatalytic materials (Hydrogenase and polymer [CN] organic semiconductor) were studied [4][5][6].…”

Energy-level dependent H 2 O 2 production on metal-free, carbon-content tunable carbon nitride photocatalysts

“…Also, the phosphate modification to TiO 2 was proven to effectively diminish the decomposition of H 2 O 2 under the conditions of H 2 O 2 generation [18] . Besides TiO 2 -based photocatalysts, a new type of C 3 N 3 S 3 polymeric materials was developed for catalyzing H 2 O 2 photosynthesis [19][20][21] . For example, the Cd 3 (C 3 N 3 S 3 ) 2 coordination polymer exhibited impressive photocatalytic H 2 O 2 generation in a methanol/water solution [19] .…”
