Electrocatalysis by atomic catalysts is a major focus of chemical and energy conversion effort. Although transition-metal-based bulk electrocatalysts for electrochemical application on processes have been reported frequently, anchoring the stable transition-metal atoms (e.g. nickel iron) still remains practical challenge. Here we report strategy fabrication ACs comprising only isolated nickel/iron anchored graphdiyne. Our findings identify very narrow size distributions both (1.23 Å) iron (1.02 Å), typical sizes single-atom iron. The precision this method motivates us to develop general approach in field catalysis. Such high catalytic activity stability hydrogen evolution reactions.
