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