The synthesis of various rhenium complexes was followed by an investigation of their capacity to reduce CO2 photocatalytically to CO. Re(bpy)(CO)3X (X = Cl, NCS; bpy = 2,2'-bipyridine) was irradiated in a CO2 saturated DMF:TEOA solution in a Pyrex tube capped with a serum cap. The CO produced in the reaction was tracked using a gas chromatograph fitted with a molecular sieves column. This was followed by examining the reactivity of carboxylated Re(dcbpy)(CO)3X (dcbpy = 4,4'-dicarboxyl-2,2'-bipyridine) dye derivatives in the same manner. The objective was to attach the rhenium dye to TiO2 using it as a photoanode in a photoelectrochemical cell to produce electricity and at the same time reduce CO2 o CO catalytically. Secondly CO2 insertion into olefin-metal bonds was also studied. Molybdenum and tungsten complexes were synthesized and coupled with CO2 to form acrylic acid.
