Abstract Upgrading excess CO 2 toward the electrosynthesis of formic acid is significant research and commercial interest. However, simultaneously achieving high selectivity industrially relevant current densities ‐to‐formate conversion remains a grand challenge for practical implementations. Here, an electrically conductive zeolite support strategically designed by implanting Sn ions into skeleton structure Y, which impregnates ultrasmall In 0.2 0.8 alloy nanoclusters supercages tailored 12‐ring framework. The prominent electronic geometric interactions between nanoalloy lead to delocalization electron density that enhances orbital hybridizations active site *OCHO intermediate. Thus, energy barrier rate‐limiting formation step reduced, facilitating electrocatalytic hydrogenation acid. Accordingly, developed electrocatalyst achieves industrial‐level partial 322 mA cm −2 remarkable Faradaic efficiency 98.2% formate production stably maintains above 93% at over 102 h. This work opens up new opportunities zeolite‐based electrocatalysts from electrolysis practically accessible electrocatalysis conversion.

The practical application of electrocatalytic CO2 reduction requires adaptation to the fluctuating voltage output photovoltaic systems. However, potential-induced in-situ reconstruction catalyst complicates control and leads Faradaic efficiency (FE) instability across potential window. Here, we present a redox graphene-supported indium oxide (G-InOx), where rGO effectively regulates surface evolution InOx from In3+ In0 during reactions. multivalent In generated via lowers energy barriers for *OCHO formation dissociation, enhancing formate production. also environment, optimizing proton delivery active sites. Over wide range (−0.86 −1.37 V vs RHE), G-InOx achieves FEformate nearly 100%. This work offers straightforward efficient strategy scalable, high-performance electroreduction.
