Paragraph starter
This review highlights that the performance of single-atom catalysts is profoundly influenced by the precise atomic coordination environment provided by the carbon support. Specifically, the nature of the bonds between the metal atom and the surrounding support atoms, such as nitrogen dopants, dictates the electronic structure and thus the catalytic activity for reactions like oxygen reduction. Therefore, deliberate engineering of these coordination shells through controlled synthesis is a critical strategy for developing highly efficient electrocatalysts.
