Catalytic COx (CO and CO2) hydrogenation to valued chemicals is one of the promising approaches address challenges in energy, environment, climate change. H2O an inevitable side product these reactions, where its existence effect are often ignored. In fact, significantly influences catalytic active centers, reaction mechanism, performance, preventing us from a definitive deep understanding on structure-performance relationship authentic catalysts. It necessary, although challenging, clarify provide practical strategies tune concentration distribution optimize influence. this review, we focus how induces structural evolution catalysts assists processes, as well efforts understand underlying mechanism. We summarize discuss some representative tuning for realizing rapid removal or local enrichment around catalysts, along with brief techno-economic analysis life cycle assessment. These fundamental understandings further extended reactions CO CO2 reduction under external field (light, electricity, plasma). also present suggestions prospects deciphering controlling applications.

Abstract Electrocatalytic CO 2 reduction (CO RR) is rapidly emerging as a promising sustainable strategy for transforming into valuable fuels and chemical feedstocks, crucial step toward carbon‐neutral society. The efficiency, selectivity, stability of RR are heavily influenced by the chosen catalyst operating conditions used. Despite substantial advances in development catalysts, there scarcity comprehensive reviews focusing on influence different environments performance. This review offers detailed examination internal external environmental control strategies designed to enhance efficiency. fundamental reaction mechanisms through situ operational techniques, paired with theoretical analyses, discussed while also identifying key challenges future research directions technology. By delivering overview current state field, this highlights critical role control, mechanistic insights, practical considerations needed successful commercialization

Abstract The efficient electrocatalytic conversion of CO 2 to formate is often impeded by the high energy requirements oxygen evolution reaction (OER) and limited activity selectivity reduction (CO RR). Herein, a novel strategy enhance production substituting OER with methanol oxidation (MOR) optimizing cathodic microenvironment interfacial Cl − ions presented. Through theoretical analysis, binder‐free Bi NiOOH electrodes that achieve remarkable Faradaic efficiencies (FE ) exceeding 90% at current densities 50–250 mA·cm −2 for RR MOR, respectively, are identified. These combined experimental investigations demonstrate enrichment on electrode modulates local electronic structure, fostering conducive RR. Bi–NiOOH full cell maintains FE above industry‐level (100–300 ), enabling concurrent electrosynthesis both electrodes. This work highlights critical role anion environments in electrocatalysis provides strategic framework synergistic engineering electrochemical systems.
