However, it remains challenging because highly active oxides often undergo over\u2010oxidation and structural degradation under anodic conditions. In this study, we report a Ru\u2010modified CoMn spinel catalyst in which highly oxyphilic Ru is anchored at octahedral sites to regulate both the lattice electronic structure and the interfacial reaction environment. The strong Ru\u2010O covalency and pronounced oxygen\u2010hole character enhance the OER kinetics. Meanwhile, the highly polarized Ru centers reconstruct the interfacial hydrogen\u2010bond network and accelerate interfacial proton\u2010coupled electron transfer (PCET). The introduction of Ru can maintain structural stability during OER through restraining excessive Co oxidation and local coordination changes.
