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 gold-polyaniline (Au-PANI) nanocomposite delivered a CO2 -to-CO conversion efficiency of 85 % with a high current density of 11.6 mA cm-2 . The polyaniline shell facilitated CO2 adsorption, and the subsequent formation of reaction intermediates on the gold core contributed to the high efficiency observed.
