FIELD: precious metal technology. ^ SUBSTANCE: invention relates to a method for preparation of novel platinum-containing materials, which find always increasing demand in national economy, in particular in heterogeneous catalysis. According to invention, platinum is sublimated on high-temperature glass cloth with preliminarily deposited calcium oxide layer. Thus prepared material is a composite constituted by high-temperature glass cloth with deposited calcium oxide layer bearing (Ca,Si)O2 rods on its surface, said rods having oxidized platinum on their ends and metal particles 3-20 nm in size in underlayer. ^ EFFECT: enabled preparation of novel platinum-containing material with platinum in finely dispersed state. ^ 7 cl, 1 dwg, 1 tbl, 6 ex |
