There is a considerable research effort in the development of efficient methods for production of solar fuels from carbon dioxide. Researchers in this field have achieved the efficient coupling of light absorption and charge separation with dark catalytic reactions to produce CO and formate under a variety of conditions. However, there are still many challenges in the photocatalytic systems: the slow conversion rates; the stability; and CO2 reduction beyond CO and formate. We are currently carrying out coordinated experimental and theoretical investigation on: (1) the thermodynamic, kinetic, and photochemical properties of M-C1 and M-H species; (2) photoinduced catalytic reduction of CO2 to CO and/or formate, and ultimately to methanol following the concept of coupled proton and hydride-ion transfer reactions; and (3) photochemical CO2 reduction in supercritical CO2 or other media in order to speed up the bond formation and cleavage reactions for production of fuels. Selective topics will be presented.
