 The study presents a new approach to improve the efficiency of hydrogen evolution reaction, HER, through abstract electrocatalysis using RU-RH2 bimetaline non-airing with structural defects. The synthesis method involves a mixed solvent strategy and results in high mass activity at minus 0.05 and minus 0.07v, surpassing the commercial PD catalyst. Additionally, the bimetaline shows stable hydrogen bubble evolution after 30,000 potential cycles in acid media. The study also highlights the outstanding performance of RU-RH2 bimetaline in alkaline and neutral media, outperforming other reported HER catalysts. Atomic scale structure observation and density functional theory calculations reveal that grain boundaries and symmetry breaking of RU-RH2 bimetaline weaken the adsorption strength of atomic hydrogen and facilitate electron transfer and reactant adsorption, leading to enhanced HER electrocatalytic performance in all pH values.
