In one preferred embodiment, a photocatalyst for conversion of carbon dioxide and water to a hydrocarbon and oxygen comprises at least one nanoparticulate metal or 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 600&#xb0; C. to form a nanoparticulate carbon-coated metal or metal oxide material, and subsequently substantially removing the carbon coating. The precursor material comprises a solid, solvent-free salt comprising a metal ion and at least one thermally decomposable carbon- and oxygen-containing counter-ion, and the metal of the salt is selected from the group consisting of Mn, Ti, Sn, V, Fe, Zn, Zr, Mo, Nb, W, Eu, La, Ce, In, and Si.

Autogenic reaction synthesis of photocatalysts for solar fuel generation

A coal liquefaction process employing a first stage liquefaction step catalyzed by a soluble molybdenum-containing organophosphorodithioate catalyst is disclosed. In some embodiments, two consecutive liquefaction steps employ a molybdenum-containing organophosphorodithioate catalyst operating at a relatively high liquefaction temperature. In other embodiments, a second liquefaction process step operating at a relatively low temperature employs a hydrocracking catalyst to upgrade materials obtained from the first soluble catalyst liquefaction step. In some embodiments, an interstage gas separator removes gases such as carbon dioxide produced in the first liquefaction step from a partially liquefied mixture prior to further liquefying the mixture in the second liquefaction step.
