FIELD: catalyst production. SUBSTANCE: catalyst consisting of supported catalytically active mass is prepared by thermally spraying onto support a material containing reactive precursor of at least one component of catalytically active mass, which precursor is further subjected to transformation to give desired component. Inactivation of heat-sensitive component during spraying process can be avoided. EFFECT: increased specific surface of catalyst. 19 cl, 1 dwg, 2 tbl, 4 ex
