General aggregation-induced deposition approach for creating asymmetric single-atom catalysts

Abstract

We introduce a general aggregation-induced deposition approach for synthesizing high-density Co single atom sites with precise atomic configuration on an N,O co-doped hollow carbon matrix (Co-SAs/NHC). Moreover, this strategy can also be applied to fabricate ten different metal single-atom catalysts. This design leverages the interactions between Co sites across adjacent carbon layers, enhancing the structural and chemical durability and the catalytic performance of the Co-SAs/NHC-based zinc–air battery.
