Catalytic chemical conversion of carbon dioxide gas combined with a hydrocarbon gas, comprising natural gas, methane, ethane, propane, butane or pentane, over a transition metal oxide, produces organic solvent products. The process converts oxidized carbon compounds to valued organic products and can reduce or eliminate the carbon footprint of industrial electric power generation industry. Catalytic processes are taught for chemical conversion of oxides of carbon, principally carbon dioxide (formed by combustion of hydrocarbons), to solvent compounds comprising acetone, butanol, pentane and related organic products. The catalysts are transition metal oxides, selected from the group comprising manganese, iron and cobalt or combinations thereof.

Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and a supported transition metal catalyst—containing molybdenum, tungsten, or vanadium—are irradiated with a light beam at a wavelength in the UV-visible spectrum, optionally in an oxidizing atmosphere, to form a reduced transition metal catalyst, followed by hydrolyzing the reduced transition metal catalyst to form a reaction product containing the alcohol compound and/or the carbonyl compound.
