  • Reactive capture bypasses CO2 regeneration, enabling efficient CO production but with low Faradaic efficiency. The authors report a Ni–N3 molecular catalyst that resists amino acid adsorption and promotes efficient CO production in amino-acid systems.

  • The electrocatalytic upgrading of CO2/CO provides a promising route to produce carbon-neutral alcohols but suffers from product loss to crossover and dilution. Here, the authors report on a CO reduction electrolyzer that recovers over 85% of alcohol without dilution, which is then scaled to 800 cm2.

  • Electrochemical COx reduction to multi-carbon products is hindered by low energy efficiency, in part due to sluggish ion transport across charge-selective membranes used in electrolysers. Here the authors use a porous, non-charge-selective separator that enhances ion transport and improves performance for CO electrolysis.

  • While the high concentration of CO2 in flue gas makes it an attractive feedstock for electrocatalytic production of useful molecules, SO2 contaminants can poison catalysts. Here the authors report a polymer/catalyst/ionomer heterojunction design with hydrophobic and hydrophilic domains that improves the SO2 tolerance of a Cu catalyst.

  • Acidic CO2 electroreduction is carbon efficient but suffers from low energy efficiency and selectivity. Here an interfacial cation matrix is developed to enrich alkali cations and increase the local pH at a Cu–Ag catalyst surface, improving efficiency. A 45% CO2-to-ethanol Faradaic efficiency and 15% energy efficiency for ethanol production are achieved.

  • The electrosynthesis of CO via integrated capture and conversion of dilute CO2 suffers from low energy efficiency. Here, the authors report an amino acid salt-based system that employs a single-atom catalyst and operates at an elevated temperature and pressure, which enables efficient CO production.
