Using the electrochemical CO2 reduction reaction (CO2RR) with Cu-based electrocatalysts to achieve carbon-neutral cycles remains a significant challenge because of its low selectivity and poor stability. Modulating surface electron distribution by defects engineering or doping can effectively improve CO2RR performance. Herein, we synthesize electrocatalyst Vo-CuO(Sn) nanosheets containing oxygen vacancies Sn dopants for application in CO2RR-to-CO. Density functional theory calculations confirm that incorporation atoms substantially reduces energy barrier *COOH *CO intermediate formation, which results high efficiency, overpotential, superior stability CO conversion. This possesses Faraday efficiency (FE) 99.9% at overpotential 420 mV partial current density up 35.22 mA cm-2 -1.03 V versus reversible hydrogen electrode (RHE). The FECO could retain over 95% within wide potential area from -0.48 -0.93 RHE. Moreover, obtain long-term more than 180 h only slight decay activity. Therefore, this work provides an effective route designing environmentally friendly

Membrane electrode assemblies enable CO2 electrolysis at industrially relevant rates, yet their operational stability is often limited by formation of solid precipitates in the cathode pores, triggered cation crossover from anolyte due to imperfect ion exclusion anion exchange membranes. Here we show that concentration affects degree movement through membranes, and this substantially influences behaviors copper catalysts catholyte-free electrolysers. Systematic variation (KOH or KHCO3) ionic strength produced a distinct switch selectivity between either predominantly CO C2+ products (mainly C2H4) which closely correlated with quantity alkali metal (K+) crossover, suggesting cations play key role C-C coupling reaction pathways even cells without discrete liquid catholytes. Operando X-ray absorption quasi situ photoelectron spectroscopy revealed Cu surface speciation showed strong dependence on concentration, wherein dilute anolytes resulted mixture Cu+ Cu0 species, while concentrated led exclusively under similar testing conditions. These results cells, effects (including unintentional ones) significantly influence pathways, important consider future development devices.
