Abstract Single-atom catalysts (SACs) exhibit intriguing catalytic performance owing to their maximized atom utilizations and unique electronic structures. However, the reported strategies for synthesizing SACs generally have special requirements either anchored metals or supports. Herein, we report a universal approach of electrochemical deposition that is applicable wide range supports fabrication SACs.
