CO2 electrolyzers have progressed rapidly in energy efficiency and catalyst selectivity toward valuable chemical feedstocks fuels, such as syngas, ethylene, ethanol, methane. However, each component within these complex systems influences the overall performance, further advances needed to realize commercialization will require an approach that considers whole process, with electrochemical cell at center. Beyond boundaries, electrolyzer must integrate upstream feeds downstream separation processes a way minimizes product intensity presents viable use cases. Here we begin by describing sources, their intensities, impurities. We then focus on cell, most common system architectures, systems. evaluate savings feasibility of alternative approaches including integration capture, direct conversion flue gas two-step via carbon monoxide. pathways minimize separations produce concentrated streams compatible existing sectors. Applying this comprehensive upstream-to-downstream approach, highlight promising routes, outlook, for reduction.

To utilize intermittent renewable energy as well achieve the goals of peak carbon dioxide emissions and neutrality, various electrocatalytic devices have been developed. However, reactions, e.g., hydrogen evolution reaction/oxygen reaction in overall water splitting, polysulfide conversion lithium–sulfur batteries, formation/decomposition lithium peroxide lithium–oxygen nitrate reduction to degrade sewage, suffer from sluggish kinetics caused by multielectron transfer processes. Owing merits accelerated charge transport, optimized adsorption/desorption intermediates, raised conductivity, regulation microenvironment, ease combine with geometric characteristics, built-in electric field (BIEF) is expected overcome above problems. Here, we give a Review about very recent progress BIEF for efficient electrocatalysis. First, construction strategies characterization methods (qualitative quantitative analysis) are summarized. Then, up-to-date overviews engineering electrocatalysis, attention on electron structure optimization microenvironment modulation, analyzed discussed detail. In end, challenges perspectives proposed. This gives deep understanding design electrocatalysts next-generation storage devices.

Electrochemical CO2 reduction to multicarbon products faces challenges of unsatisfactory selectivity, productivity, and long-term stability. Herein, we demonstrate electroreduction in strongly acidic electrolyte (pH ≤ 1) on electrochemically reduced porous Cu nanosheets by combining the confinement effect cation synergistically modulate local microenvironment. A Faradaic efficiency 83.7 ± 1.4% partial current density 0.56 0.02 cm-2, single-pass carbon 54.4%, stable electrolysis 30 h a flow cell are demonstrated for aqueous consisting sulfuric acid KCl with pH 1. Mechanistically, accumulated species (e.g., K+ OH-) Helmholtz plane account selectivity activity toward kinetically reducing proton coverage thermodynamically favoring conversion. We find that cations facilitate C-C coupling through interaction between key intermediate *OCCO.

Abstract Atomically dispersed metal catalysts have triggered great interest in the field of catalysis owing to their unique features. Isolated single or few atoms can be anchored on substrates via chemical bonding space confinement maximize atom utilization efficiency. The key challenge lies precisely regulating geometric and electronic structure active centers, thus significantly influencing catalytic properties. Although several reviews been published preparation, characterization, application single‐atom (SACs), comprehensive understanding SACs, dual‐atom (DACs), atomic clusters has never systematically summarized. Here, recent advances engineering local environments state‐of‐the‐art DACs, for enhanced performance are highlighted. Firstly, various synthesis approaches presented. Then, special attention is focused elucidation terms state coordination structure. Furthermore, a summary isolated applications thermocatalysis, electrocatalysis, photocatalysis provided. Finally, potential challenges future opportunities this emerging This review will pave way regulate microenvironment site boosting processes.
