Carbon Dioxide Reduction to Alcohols using Perovskite‐Type Electrocatalysts

Electrochemical reduction of under ambient conditions to methanol, ethanol, and n‐propanol is reported at perovskite‐type electrocatalysts when incorporated into gas diffusion electrodes. In the absence of copper at the perovskite B lattice site, no activity was found. This investigation resulted in the identification of electrochemical conditions whereby perovskite‐type electrocatalysts could achieve cumulative Faradaic efficiencies for reduction to methanol, ethanol, and n‐propanol up to ≅40% at current densities of 180 mA/cm 2 .
