FIELD: chemistry. ^ SUBSTANCE: invention relates to catalytic chemistry, namely to catalysts of deep oxidation of hydrocarbons and CO to carbon dioxide and water, and to method of its production. Invention covers the method of producing thermally stable catalyst of complete oxidation of hydrocarbons and carbon monoxide based of tin dioxide of common formula MeOxSnO2, if Me = Zn2+; Cu2+; Mn2+; Co2+; Ni2+; Pb2+; Cd2+ or Me2O3ÇxSnO2, if Me2= Fe3+; Ce3+; La3+; Cr3+, where x=1-5 for divalent metals, and x=2-10 for trivalent metals. Note here that catalyst is produced by introducing in -Sn(OH)4 of readily degradable metal salts, i.e. nitrates, acetates, or by co-precipitation of the solution containing SnCl4 and salt of Me -nitrates, chlorides, acetates, sulphates, by ammonium or alkaline solution. ^ EFFECT: higher activity of catalyst at increased temperatures. ^ 21 ex, 1 tbl |
