Summary: To enhance the hydrogen storage performance of Mg-rich alloys, element Sc is introduced into Mg-Y-Zn alloy, which effectively enhances the dehydrogenation kinetics and facilitates the decomposition of YH3. Sc-doping weakens H2 sorption but ensures H atom diffusion in the Mg matrix. Sc substitution makes it difficult for hydrogen to diffuse deeper into the samples, resulting in a large ratio of unhydrided Mg.

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.
