摘要：

Methane is activated at room temperature and atmospheric pressure on TiO2, supported molybdena catalyst excited by band gap illumination. With pure TiO2, complete oxidation to CO2 is observed in the presence of oxygen. The deposition of 4% molybdena has a pronounced effect on methane activation, partial oxidation to CO becoming a competing pathway. CO is the major oxidation product if TiO2 loaded with both MoO3 and H4SiW12O40 is used as a catalyst. MoO3 used alone or in conjunction with Al2O3 or SiO2 as carriers exhibits poor activity in the photoactivation of methane.
