Turing topologies regulate interfacial microenvironments for industrial‐level CO ₂ ‐to‐formate electrosynthesis

Achieving industrial‐level electrochemical CO 2 reduction to formate remains a significant challenge due to limitations in catalyst selectivity and interfacial proton management at high current densities. In a recent study, Prof. Guo and colleagues report the development of Turing‐structured electrocatalysts, which incorporate reaction‐diffusion‐inspired topologies to engineer mesoscale surface patterns. This design enables precise modulation of the interfacial microenvironment, enhancing CO 2 activation and suppressing competing hydrogen evolution. The resulting catalysts achieve efficient and stable CO 2 ‐to‐formate conversion under industrially relevant conditions, offering a promising strategy for scalable carbon‐neutral chemical production.
