The electrochemical CO2 reduction (eCO2RR) to valuable chemicals offers a promising method combat global warming by recycling carbon. Among the possible products, syngas—a CO and H2 mixture—is especially for industrial reactions. use of Room Temperature Ionic Liquids (RTILs) electrolytes presents pathway eCO2RR because lower overpotential required increased solubility with respect aqueous ones. Ensuring constant CO/H2 production is essential, it relies on both catalyst reactor design. This study explores in RTIL mixtures 1-butyl-3-methyl imidazolium trifluoromethanesulfonate (good conversion) acetate capture), various amounts water as proton source. We evaluated syngas stability across different cells ion exchange membranes after determining appropriate electrolyte mixture suitable ratio near 1:1. two-chamber cell configuration outperformed single-cell designs reducing oxidative RTILs degradation by-products formation. Using bipolar membrane (BPM) forward mode led catholyte acidification, causing an increase HER relative over time, confirmed Multiphysics modeling. Conversely, anionic (AEM) maintained extended periods. work guidelines generation RTIL-based systems from waste-CO2 reduction, which can be useful other green chemical synthesis processes.

Abstract Electrocatalytic CO 2 reduction reaction (CO RR) in membrane electrode assembly (MEA) systems is a promising technology. Gaseous can be directly transported to the cathode catalyst layer, leading enhanced rate. Meanwhile, there no liquid electrolyte between and anode, which help improve energy efficiency of whole system. The remarkable progress achieved recently points out way realize industrially relevant performance. In this review, we focus on principles MEA for RR, focusing gas diffusion electrodes ion exchange membranes. Furthermore, anode processes beyond oxidation water are considered. Besides, voltage distribution scrutinized identify specific losses related individual components. We also summarize generation different reduced products together with corresponding catalysts. Finally, challenges opportunities highlighted future research.

Abstract Oxygen evolution reaction (OER) is the anodic half‐reaction for crucial energy devices, such as water electrolysis, metal–air battery, and electrochemical CO 2 reduction. Fe‐based materials are recognized one of most promising electrocatalysts OER because its extremely low price high activity. In particular, iron oxyhydroxide (FeOOH) not only highly active toward OER, but also widely accepted true species plenty converted into FeOOH during test. Herein, recent advances FeOOH‐based nano‐structure application in reviewed.
