Research Abstract

We have investigated the photo-reduction of carbon dioxide in room temperature ionic liquids. Using triethanolamine as the electron donor, under the existence of rhenium catalysis the photo-reduction of carbon dioxide has been tested for several ionic liquids with a variety of cations and anions at different temperatures and pressures. It has been revealed that the solutions of imidazolium cations of short alkyl-chains with hydrophobic anions are suitable for the photo-reduction of carbon dioxide.
