Abstract
Here it was demonstrated that the decoration of gold (Au) with polyaniline is an effective approach in increasing its electrocatalytic reduction of CO₂ to CO. The core-shell-structured goldpolyaniline (Au–PANI) nanocomposite delivered a CO₂–CO conversion efficiency of 85% with a high current density of 11.6 mAcm¯². The polyaniline shell facilitated CO₂ adsorption, and the subsequent formation of reaction intermediates on the gold core contributed to the high efficiency observed.
