摘要：

TiO2:MoO3 nanocomposites with MoO3 content in the range of 0.1-10 mol.% were synthesized using sol-gel technology. The role of the structural peculiarities of TiO2:MoO3 composite in hydrogen adsorption and catalytic oxidation was discussed. Possibility of the selective oxidation of hydrogen in the presence of methane in the atmosphere was demonstrated.
