Possibility of employment of multioxide structures on the basis of doped titanium dioxide, 
obtained by the sol-gel method as gas sensor primary elements was studied. It was established 
that the varying of the chemical nature of the doping material (indium, gallium, aluminum, 
iron(III), molybdenum oxides, etc.) permits to improve sensitivity of primary elements towards 
hydrogen in gas-air mixtures with hydrocarbons. Comparison of gas sensing properties of 
multioxide systems on the basis of titanium dioxide with different chemical nature and the 
quantity of doping materials was carried out. TiO2–MoO3 system with 1 mol.% of molybdenum 
was established to display the best gas sensing properties among the researched systems.
