Co-electrolysis of CO2 and formaldehyde to ethanol: An inspiring asymmetric C−C coupling pathway

Selectively producing a target ethanol product is highly desired but challenging, especially when using CO2 as a feedstock only. In this issue of Chem Catalysis, Han and co-workers describe a co-electrocatalytic conversion of CO2 and formaldehyde (FA) toward ethanol, which expands the scopes of C−C coupling routes for CO2 utilization.
