Summary: Compared to HER under acidic conditions, alkaline HER involves more complex kinetic steps, including the adsorption and cleavage of water molecules. Defect and interface engineering are important methods to enhance alkaline HER. In this study, a catalyst composed of a defective amorphous carbon loaded with Ru nanoparticles wrapped around a carbon nanotube sponge network was prepared. The presence of amorphous carbon promotes uniform loading and limits the growth of Ru nanoparticles, while the introduction of oxygen defects improves charge transport capacity and catalytic performance. The optimized catalyst exhibited excellent stability and activity, with low overpotentials under both alkaline and acidic conditions, surpassing most reported Ru-based catalysts. These findings provide innovative and feasible ideas for the design and preparation of loaded catalysts, contributing to the development of high-performance electrochemical catalysts.
