Abstract

TOF, and minimal charge-transfer resistance (5.39 Ω), outperforming control samples and commercial Pt/C. The catalyst exhibited outstanding stability with only 2.1% current decay after 50 h. Mechanistic studies indicated that the multi-d orbital electronic interactions in the alloy can regulate the adsorption capacities of H and OH species, thereby enhancing its alkaline HER catalytic activity.
