Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...
