  • Producing valuable hydrocarbons electrochemically from carbon monoxide (CO) is an energy-efficient pathway, but reliance on costly pure CO as a feedstock limits its economic viability. This article shows that abundant CO-rich syngas can be directly used to synthesize ethylene.

  • 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.

  • 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.

  • Current industrial methods of ethylene glycol production generate substantial CO2 emissions. Here electrocatalytic ethylene-to-ethylene glycol conversion is coupled to electrochemical CO2 capture, decreasing carbon intensity by an order of magnitude.

  • Electrosynthesis of n-propanol from CO has been limited by poor selectivity and low product concentration. Here a Sn–Cu catalyst/carbon/ionomer heterojunction is prepared where the adjacent atomic active sites favour the coupling of C1 and C2 intermediates to C3 product with 47% Faradaic efficiency and the reversal of electro-osmotic drag concentrates the product to 30 wt%.

  • 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.
