Claim Text:
1. A photocatalyst for conversion of carbon dioxide and water into a hydrocarbon and oxygen, the photocatalyst comprising at least one metal oxide material that is substantially free of a carbon coating, prepared by heating a metal-containing precursor compound in a sealed reactor under a pressure autogenically generated by dissociation of the precursor material in the sealed reactor at a temperature of at least about 400° C. to form a nanoparticulate carbon-coated metal or metal oxide material, and subsequently substantially removing the carbon coating; wherein: the precursor material comprises a solid, solvent-free salt comprising a metal on and at least one thermally decomposable carbon- and oxygen-containing counter-ion; the metal oxide consists of a mixture of SnO the TiO the SnO
