The quantum efficiency to reduce of CO2 to CO photocatalytically using visible light will be described. Irradiation of saturated CO2 solutions of dimethylformide:triethanolamine (DMF:TEOA) containing two different dyes are compared. The behavior of the dye Re(dcbpy)(CO)3X (X = Cl-, NCS-,dcbpy = 4,4'-dicarboxyl-2,2'-bipyridine) attached to TiO2 was examined with the goal of simultaneously producing electricity and reduction of CO2 to CO is compared to the parent catalyst, Re(bpy)(CO)3X, where bpy is 2,2'-bipyridine. The CO produced in the reaction was tracked using gas chromatograph fitted with a molecular sieves column. Conversion of CO2 to acrylic acid by way of a molybdenum catalyst will also be shown as a possible route for CO2 up-conversion.
