Effective photo-reduction of carbon dioxide by using ionic liquids

本文研究了室温离子液体中二氧化碳的光还原反应。以三乙醇胺为给电子体，在乙醇催化剂存在下，在不同温度和压力下，考察了几种具有不同阳离子和阴离子的离子液体对CO2的光还原反应。研究表明，短烷基链咪唑阳离子与疏水阴离子的溶液适合于二氧化碳的光还原反应。

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.
