ABSTRACT Electrochemical CO 2 reduction reaction (CO RR) has received great attention to solve ‐ induced global warming and carbon neutrality. It is essential enhance the electrochemical RR selectivity, activity, long‐term stability for sustainable manufacturing of specific chemicals via RR. To produce multi‐carbon (C 2+ ) chemicals, Cu‐based heterogeneous catalysts have been developed in terms defect engineering, morphological design, facet control. Despite substantial efforts design efficient catalysts, there exist inevitable structural changes with continuous dissolution redeposition during This reconstruction modifies as‐synthesized into an unpredictable structure leads active site.

Dynamic protonation of ligand sites in molecular catalysts enhances electrochemical CO ₂ reduction

Science Advances, Journal Year: 2025, Volume and Issue: 11(17)

Published: April 25, 2025

Molecular catalysts with functional group decorations are promising for electrocatalytic CO 2 reduction to produce valuable chemicals and fuels. Using nickel phthalocyanine derivatives cyano, methoxy, dimethylamino groups, this study unveils why decorating molecular either electron-donating or electron-withdrawing groups can enhance their activity. Notably, the group–decorated catalyst demonstrated stable nearly 100% -to-CO selectivity over a wide potential range high partial current densities up 300 milliamperes per square centimeter. Theoretical in situ spectroscopic analyses revealed critical role of dynamic protonation ligand sites activating metal center, which be facilitated by decoration groups. Conversely, although requiring higher energy protonation, synergy between centers protonated sites, favoring formation key *COOH intermediates improving at bias. This underscores importance optimizing functionalized enhanced RR
