The electrochemical CO2 reduction reaction (ECO2RR) is a promising strategy for converting into high-value chemical products. However, the synthesis of effective and stable electrocatalysts capable transforming specified product remains huge challenge. Herein, we report template-regulated preparation Bi2O3-derived nanosheet catalyst with abundant porosity to achieve expectantly efficient CO2-to-formate conversion. resultant porous bismuth (p-Bi) not only exhibited marked Faradaic efficiency formate (FEformate), beyond 91% in broad potential range from −0.75 −1.1 V H-type cell, but also demonstrated an appreciable FEformate 94% at high current density 262 mA cm–2 commercially important gas diffusion cell. State-of-the-art X-ray absorption near edge structure spectroscopy (XANES) theoretical calculation unraveled distinct production performance p-Bi catalyst, which was cocontributed by its smaller size, plentiful structure, stronger Bi–O bond, thus accelerating promoting subsequent formation intermediates. This work provides avenue fabricate bismuth-based catalysts planar morphologies portfolio applications.

Abstract Formic acid (FA) has emerged as a promising candidate for hydrogen energy storage due to its favorable properties such low toxicity, flammability, and high volumetric capacity under ambient conditions. Recent analyses have suggested that FA produced by electrochemical carbon dioxide (CO 2 ) reduction reaction (eCO RR) using low‐carbon electricity exhibits lower fugitive (H emissions global warming potential (GWP) during the H carrier production, transportation processes compared those of other alternatives like methanol, methylcyclohexane, ammonia. eCO RR can enable industrially relevant current densities without need pressures, temperatures, or auxiliary sources. However, widespread implementation is hindered requirement highly stable selective catalysts. Herein, aim explore evaluate catalyst engineering in designing nanostructured catalysts facilitate economically viable production FA.

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.
