The　development　of　high-kinetic　catalysts　for　the　hydrogen　evolution　reaction　(HER)　in　a　neutral　electrolyte　is　of　great　importance　but　unfortunately　remains　a　challenge　so　far.　Herein,　we　report　hybrids　with　abundant　Ru-S-Sb　bonds　and　engineered　ultrathin　antimonene　(Ru-S-Sb/antimonene)　as　highly　kinetic,　active,　stable　electrocatalysts　for　the　HER　in　an　aqueous　neutral　electrolyte.　Experiments　and　density　functional　theory　(DFT)　calculations　reveal　that　Ru-S-Sb　bonds　coupling　with　antimonene　synergistically　work　to　promote　HER　activity.　The　present　study　brings　us　one　step　closer　to　understand　the　structure-composition-property　relationships　and　practical　electrolytic　H-2　production.
