Investigation of direct conversion of methane to transportation fiiels has been an ongoing effort at PETC for over 10 years. One of our current areas of research is the conversion of methane to methanol, under mild conditions, using li t, water, and a semiconductor photocatalyst. Research in our laboratory is directed toward ad ting the chemistry developed for photolysis of water to that of methane conversion. The reaction sequence of interest uses visible light, a doped tungsten oxide photocatalyst and an electron transfer molecule to produce a hydroxyl i cal. Hydroxyl t cal can then react with a methane molecule to produce a methyl radical. In the preferred reaction pathway, the methyl radical then reacts with an additional wata- molecule to produce methanol and hydrogen.

Mixed Ti-W oxides, after deposition of Pt, are active in the mineralization of toluene with sunlight excitation due to the low bandgap (2.7 eV) caused by the presence of both W and Pt in the anatase structure [87]. Vanadium was also used to prepare visible light active photocatalysts in dye degradation [88]. 

Ce02 was found to be a good photocatalysts working under visible light for degradation of dyes through the production of reactive 02- species [118]. 

C-doped Ti02 was employed for the photocatalytic removal of NOx. The presence of carbon, in the form of coke-like species, was responsible for visible light absorption and thus for the good activity of the photocatalyst under green light irradiation [133]. 

Bare CuOx-supported nanostructures showed some activity in H 2 production from methanol-water mixture under UV-visible irradiation [180]. Ni is also used as a dopant, and small amounts (1 wt.%) of this element in mesoporous titania guarantee good activity in water-methanol mixtures under UV-visible light [181]. Indium-tantalum oxide Ni-doped materials also provided photocatalysts with promising efficiencies for direct water splitting [182]. TiOz nanotubes doped with Ir and Co nanopartides were effective for visible light water splitting even in the absence of...
