Unraveling the electronegativity-dominated intermediate adsorption on high-entropy alloy electrocatalysts

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: May 13, 2022

Abstract High-entropy alloys have received considerable attention in the field of catalysis due to their exceptional properties. However, few studies hitherto focus on origin outstanding performance and accurate identification active centers. Herein, we report a conceptual experimental approach overcome limitations single-element catalysts by designing FeCoNiXRu (X: Cu, Cr, Mn) system with various sites that different adsorption capacities for multiple intermediates. The electronegativity differences between mixed elements HEA induce significant charge redistribution create highly Co Ru optimized energy barriers simultaneously stabilizing OH * H intermediates, which greatly enhances efficiency water dissociation alkaline conditions. This work provides an in-depth understanding interactions specific opens up fascinating direction breaking scaling relation issues multistep reactions.
