Electrocatalytic reduction of carbon dioxide by a polymeric film of rhenium tricarbonyl dipyridylamine
摘要:
A dipyridylamine ligand with a pendant pyrrole (N-(3-N,N'-bis(2-pyridyl)propylamino)pyrrole, PPP) and its corresponding rhenium(I) complex, Re(CO)(3)(kappa(2)-N,N-PPP)Cl, were synthesized. The structure of Re(CO)(3)(kappa(2)-N,N-PPP)Cl was determined by X-ray crystallography. Electrochemical polymerization of the pyrrole moiety resulted in the immobilization of poly[Re(CO)(3)(kappa(2)-N,N-PPP)Cl] film onto a glassy carbon electrode, which exhibited electrocatalytic activity for the reduction of CO2 to CO.
