Ultra-stable oxygen species in Ag nanoparticles anchored on g-C3N4 for enhanced electrochemical reduction of CO2

Oxide-derived silver catalysts containing stable oxygen species have been proved to be efficient for the electrochemical reduction reaction of CO2 (CO2RR) due to their enhanced binding energy to *COOH intermediate. Here we developed a hydrothermal decomposition method to synthesize silver nanoparticles (NPs) supported on carbon nitride (Ag/g-C3N4) from silver oxide (Ag2O) precursor. The obtained Ag/g-C3N4 electrocatalyst is capable of producing...
