Traditional CO2 reduction systems often fail in an alkaline environment due to the interaction of with a high-pH electrolyte, where carbonate and bicarbonate ion formation results potassium-containing salt precipitation. The presence crystals causes selectivity electrolyzer toward conversion. Here, critical operational variables, which elicit salting out process, are investigated (i.e., transport). When exceeds current density, H2 evolution dominates formation, is confirmed by postmortem cross-sectional SEM-EDS electrode. density decreases increasing membrane thickness or anolyte ionic strength. Cathode mediated unmitigated crossover cations from cathode across anion exchange membrane, through imperfectly excluded. It likely that electric field-driven migration promotes increase concentration potassium until, at for arrangement, ions solubility limit KHCO3, leading

Porous nanomaterials find wide-ranging applications in modern medicine, optoelectronics, and catalysis, playing a key role today's effort to build an electrified, sustainable future. Accurate situ quantification of their structural surface properties is required model performance improve design. In this article, we demonstrate how assess the porosity, area utilization nanoporous soft-landed copper oxide catalyst layer/carbon interface, which otherwise difficult resolve using physisorption or capacitance-based methods. Our work employs electron tomography characterize three-dimensional structure layer combines it with soft X-ray absorption spectroscopy lead underpotential deposition data probe stability under potential bias. The analysis proves that significant share original exploited, thus explains product distribution crossover trends electrosynthesis C2+ products from carbon monoxide.

Abstract This study demonstrates the electrochemical reduction of carbon monoxide (COR) at high current densities in a zero‐gap electrolyzer cell and stack. By systematically optimizing both commercially available membrane electrode assembly components (including binder content gas diffusion layer) operating conditions, we could perform COR up to 1.4 A cm −2 with maximum C 2+ selectivity 90%. We demonstrated scale‐up 3 × 100 2 stack that can sustain stable operation 1 for several hours without significant performance decay total ~80% an ethylene ~40%. provide critical insights into holistic optimization key system parameters, using special catalysts or surface additives, which pave way scalable industrially viable processes.
