Comprehensive Summary

A novel electrocatalyst, Ni-Co/β-Mo2C@C, was rationally designed to enhance the efficiency of the hydrogen evolution reaction (HER) in this work. Assembled with two-dimensional Ni-Co nanosheets onto Mo2C nanorods coated with a thin carbon shell, the catalyst demonstrates remarkable performance, including low overpotential (η10 = 57 mV) and reduced Tafel slope (63 mV·dec–1) in 0.5 mol·L–1 H2SO4 electrolyte. This innovative design strategy provides abundant active sites and efficient electron/ion transport pathways, effectively shortening reactant diffusion distances and enhancing electrocatalytic activity. Additionally, the carbon shell coating protects the catalyst from etching and agglomeration, ensuring its durability. This work presents a promising approach for engineering highly efficient metal carbide-based HER catalysts through tailored composition and nanostructure design.
