Polymeric ionomers near the catalyst surface of CO2 reduction reaction (CO2RR) electrodes affect their efficiency; however, multifaceted properties complicate structure–activity relationship elucidation. Here, we synthesized polycarbazole-based anion-exchange (QPC) bearing varying functionalized side chains to explore this relationship. Comprehensive analysis in physicochemical properties, electrochemical activity, and operando ATR-SEIRAS revealed that functional group modification significantly influenced intrinsic ionomer thereby affecting Ag microenvironments interfacial water structures, kinetics protonation step for CO2RR hydrogen evolution (HER). Notably, QPC-trimethyl phosphonium (TMP) induced favorable having a high proportion strong H-bonded with low Stark tuning slopes, which inhibit HER promote CO2RR. A CO Faradaic efficiency (>90%) was maintained using QPC-TMP membrane electrode assembly, even under concentrations (100–15%) elevated temperatures (28–72 °C). These findings suggest catalytic environment can be optimized by fine-tuning structure, contributing advancement high-performance ionomers.

Abstract The electrochemical CO 2 reduction reaction (CO RR) holds significant promise as a sustainable approach to address global energy challenges and reduce carbon emissions. However, achieving long‐term stability in terms of catalytic performance remains critical hurdle for large‐scale commercial deployment. This mini‐review provides comprehensive exploration the key factors influencing RR stability, encompassing catalyst design, electrode architecture, electrolyzer optimization, operational conditions. We examine how degradation occurs through mechanisms such valence changes, elemental dissolution, structural reconfiguration, active site poisoning propose targeted strategies improvement, including doping, alloying, substrate engineering. Additionally, advancements modifications membrane enhancements, are highlighted their role improving stability. Operational parameters temperature, pressure, electrolyte composition also play crucial roles extending lifespan reaction. By addressing these diverse factors, this review aims offer deeper understanding determinants RR, laying groundwork development robust, scalable technologies efficient dioxide conversion.
