## Xe lamp irradiation of various TIOz photocatalysts suspended in an ethanol-water mixture can produce hydrogen, methane and acetaldehyde at room temperature. The quantum yield of hydrogen production was increased greatly by supporting metals or metal complexes on the TiOz surface. amounting to 3

One promising application of supercritical water as reaction medium is the selective oxidation from methane to methanol. Methanol is one of the most important intermediates in the chemical industry with a worldβwide production capacity of about 29 million tons per year (1996). A direct conversion of

**A group of ironβdoped novel oxides** of cerium, terbium, and praseodymium are reported to produce hydrogen at relatively low temperatures through a cycling twoβstep reaction process without catalyst. Iron doping in the oxides not only stimulates surface activity, but also lowers the reduction temp
