 This research has demonstrated the potential of using defective perovskite materials as catalysts for the electrochemical conversion of carbon dioxide, CO2, into valuable multi-carbon compounds. The use of these materials allows for more efficient production of C2 plus compounds through the CO2 reduction reaction, CO2RR, which is driven by the presence of CO2 molecules at the catalytic site. The presence of these defective sites, created by the leaching of lanthanum atoms from the material, increases the surface area available for CO2 adsorption, leading to faster CC bonding reactions and higher yields of C2 plus compounds.
