Selective and energy-efficient electrosynthesis of ethylene from CO2 by tuning the valence of Cu catalysts through aryl diazonium functionalization
Although progress has been made in producing multi-carbon products from the electrochemical reduction of CO2, the modest selectivity for ethylene (C2H4) leads to low energy efficiency and high downstream separati...
