Hydrogen evolution performance of Co-MOF/H-g-C₃N₄ composite catalysts with different morphologies under visible light

Abstract

The importance of photocatalytic hydrogen evolution is increasing in energy research and environmental catalysis. Co-MOF, a metal-organic framework compound with a zeolite topological structure, has the advantage of a semiconductor...

Visible light-active binary metal ion containing functional triazine metallopolymers as a stable p-type photo-electrocatalyst in protic electrolytes

“…Molecular coordination complexes, metal ion-containing polymers, and metal-organic frameworks have gained substantial attention as electrode materials due to their improved visible light absorption and electrocatalytic activity. 12,13,16,[27][28][29][30][31] The redox-active centers, which are bonded coordinatively with the metal ions of low oxidation states, and surface unsaturation are the crucial needs in the photoinduced-PCET catalysis. In this class of compounds, photoactivity and band gap modulation could be achieved by modifying the organic ligands and the metal center.…”

“…Moreover, the metal-organic frameworks (MOFs) and coordination metallopolymers provide a large surface area and porous network structures, which are useful in heterogeneous electrocatalysis. [27][28][29][30][31][32] However, charge recombination and local charge trapping are the important limitations that reduce photoconversion efficiency. However, some of the MOFs exhibit poor coordination stability under extreme pH conditions.…”
