Tuning the metal-support interaction of supported metal catalysts has been found to be most effective approach modulating electronic structure and improving catalytic performance. But practical understanding charge transfer mechanism at level catalysis process remained elusive. Here, it is reported that ruthenium (Ru) nanoparticles can self-accommodate into Fe3 O4 carbon support (Ru-Fe3 /C) through interaction, resulting in robust activity toward alkaline hydrogen evolution reaction (HER). Spectroscopic evidence theoretical calculations demonstrate perturbation occurred Ru-Fe3 /C, redistribution directly influenced adsorption behavior during process. The RuO bond formed by orbital mixing changes state surface Ru site, enabling more electrons flow H intermediates (H* ) for favorable adsorption. weak binding strength also reinforces anti-bonding character H* with a recombination species H2 molecules. Because this satisfactory mechanism, /C nanoparticle catalyst demonstrated better HER stability than benchmark commercial Pt/C media.

Abstract Active and durable catalysts for hydrogen evolution reaction (HER) are of great significance developing renewable energy. Herein, crystalline/amorphous‐Ru/VO x (c/a‐Ru/VO ) heterogeneous conceived, in which the amorphous VO exposes more active sites enhances charge transport compared with counterpart a crystal phase structure, strengthening electronic interaction between metal‐support. As expected, c/a‐Ru/VO ‐500 heat treatment at 500 °C exhibits excellent HER performance under alkaline conditions, an overpotential only 33 mV 10 mA cm −2 small Tafel slope (27 dec −1 ), superior to commercial platinum/carbon (Pt/C) catalysts. Particularly, its mass activity (0.335 A mg Ru is 1.5 times greater than that Pt/C (0.224 Pt 50 mV. Also, it shows good industrial application prospects through tests high temperature, alkalinity, large current conditions. Theoretical calculations unveil there exists redistribution heterointerfaces, makes surface takes on electron‐deficient state, resulting optimization adsorption desorption different intermediates. This optimized behavior effectively reduces thermodynamic energy barrier, allowing catalyst greatly enhanced performance. The exploration provides promising strategy designing efficient HER.
