Abstract

The adsorption ofCO2to surfaces of pure and promoted noble metal films is investigated at 40 K using surface-enhanced Raman spectroscopy (SERS). The data indicate nonactivated adsorption on silver and gold, activated adsorption on potassium and a coexistence of activated and nonactivated adsorption on copper and potassium-doped silver. The activated species is identified to be a${\rm{CO}}_2^ - $surface anion.
