  • Integrating CO2 capture and electrochemical conversion may lower energy consumption relative to the separated processes, but scale-up is limited by low carbon conversion and energy-intensive solvent regeneration. Now, research shows that piperazine, alongside a Ni single-atom catalyst, allows effective, stable CO2 capture, and conversion to CO in a low-energy process.

  • Electrochemical reduction of CO2 can yield many different products; a better understanding of the key mechanisms at play is needed to guide the design of selective catalysts. Here the authors use in situ surface-enhanced Raman spectroscopy and simulations to elucidate reaction schemes for CO2 reduction to ethylene and ethanol.

  • Oxide-derived copper is well-known as a CO2 reduction electrocatalyst, yet the mechanism of its formation and the structure of the active phase remain unclear. Here the reduction of oxide-derived copper is modelled using large-scale molecular dynamics with a neural network potential, providing important insights into the removal of trapped oxygen under operating conditions.

  • The reconstruction of Cu electrocatalysts during CO2 reduction is an impediment to the stability of this technology, yet a clear picture of the species involved in this process remains elusive. Here, the authors demonstrate the presence of transient solution-based Cu(I) species and theoretically predict complexes with CO and oxalate as the likely candidates.

  • Cu-based catalysts have dominated CO2 electroreduction as a result of their unique ability to produce C2 or C3 products, while Ni has largely been excluded due to poisoning by intermediate CO. Here, inorganic Ni oxygenate-derived electrocatalysts with polarized Ni𝛿+ sites can produce multicarbon products, including C3 to C6 hydrocarbons.

  • Metal cations present in the electrolyte are known to influence the performance in CO2 electroreduction, but their specific role remains under discussion. Now, it is shown that the reaction can only take place in the presence of such cations, which are required to stabilize negatively charged reaction intermediates.
