Cu- and S-Doped Heteropolyacid CoMo as Electrocatalysts for Efficient Hydrogen Evolution.

This study employed polyoxometalate CoMo as a precursor and a two-step method to prepare carbon cloth-supported CuS-CoS-MoS materials. The morphology and structure of the materials were characterized using XRD, XPS, SEM, TEM, and other techniques. Interestingly, changes in the reducing gas during the calcination process could adjust the product morphology, thereby altering catalytic activity.

V-doped NiP nanoparticle grafted g-CN nanosheets for enhanced photocatalytic hydrogen evolution performance under visible light.

Exploring low-cost and highly active photocatalysts with noble metal-free cocatalysts is of great significance for photocatalytic hydrogen evolution under simulated sunlight irradiation. In this work, a novel V-doped NiP nanoparticle loaded g-CN nanosheet is reported as a highly efficient photocatalyst for H evolution under visible light irradiation. The results demonstrate that the optimized 7.
