Stabilization of a Co( <scp>ii</scp> ) site <i>via</i> a Co–O–Fe bridging motif for enhanced electro-oxidation of methanol to formate
We reveal a Co–O–Fe interface-mediated electron-transfer mechanism: Fe 2+ stabilizes Co 3+ and inhibits Co 4+ , promoting formate formation, while the Fe 2+ /Fe 3+ redox cycle sustains the active interface and enhances MOR activity.
