Among the worldwide priorities of scientific research the reduction of CO2
emissions and the quest for a source of sustainable energy occupy a prominent role [1]. There is a great interest in any photo-catalyst able to use the CO2 as a
chemical feedstock to produce the so-called “solar fuels” (possibly in a selective manner). In this contribution we synthesized and characterized several new Re, Mo and W organometallic complexes and evaluated their photo and electro activity towards the reduction of CO2. Their cyclic voltammetric behaviors under
Ar and under CO2 were evaluated, as
well as their catalytic activities during exhaustive electrolysis in CO2
atmosphere. Several complexes undergoes selective reduction of CO2 to
CO, and their faradic efficiency estimated by quantitative gas chromatography measurements.
Their electro- and photo-catalytic activities were evaluated also in presence of an external source of protons.
Finally, DFT calculation was employed to rationalize the electronic and photophysical properties of the complexes under study.
