Summary: The controllable adjustment of layered double hydroxide layer spacing has enabled its use as an electrode material for energy storage and electrochemical hydrogen evolution. However, lower conductivity and agglomeration have limited its large-scale application. In this study, sodium dodecyl sulfate (SDS) intercalation modification was used to construct LDH derivatives with vertically grown CoNi-SDS-LDH nanosheets on a nickel foam surface, resulting in a layered structure supported by nanowires which improved ion transport efficiency and reduced agglomeration. The electrode material demonstrated good electrochemical performance, with a cycling stability of 91% after 10,000 cycles and 98.1% performance retention after 10 hours of hydrogen evolution test. This anionic modification offers the potential for large-scale applications of LDH in flexible supercapacitors and electrocatalytic hydrogen evolution.

Summary: This study demonstrates a simple synthesis of the Ni3N/Mo2N heterostructure and investigates urea-assisted electrolytic hydrogen production. The adsorption behavior of the urea molecule is analyzed, showing that -NH2 groups preferentially adsorb on Ni3N while C=O groups preferentially adsorb on Mo2N. The Ni3N/Mo2N heterostructure optimizes urea adsorption and enhances the hydrogen evolution reaction, leading to significantly lower voltage requirements and a 7 times higher hydrogen production rate in the urea-assisted water electrolyzer.

Summary: In this study, a simple synthesis of Ni3N/Mo2N heterostructure was reported, and urea-assisted electrolytic hydrogen production was systematically investigated. It was found that the -NH2 and C=O groups of the urea molecule were more easily adsorbed on Ni3N and Mo2N, respectively.
