Precise synthesis of dual atom sites for electrocatalysis

Single atom sites are widely applied in various electrocatalytic fields due to high atom utilization, mass activity, and selectivity. They are limited in catalyzing multi-electron reactions due to their intrinsic mono-metal center feature. Dual atom sites (DASs) as promising candidate have received enormous attentions because adjacent active sites can accelerate their catalytic performance via synergistic effect. Herein, the fundamental understandings and intrinsic mechanism underlying DASs and corresponding electrocatalytic applications are systemically summarized. Different synergy dual sites are presented to disclose the structure-performance relationship with engineering the well-defined DASs on the basis…
