FIELD: chemistry. ^ SUBSTANCE: present invention relates to catalyst systems based on gold, wherein catalytically active gold is deposited onto a composite support structure. A method is described for making a heterogeneous catalyst system for oxidising CO or hydrocarbons, containing a physical vapour deposition of catalytically active gold on a composite nanoporous carrier material, obtained from ingredients which contain incoming titanium dioxide material and carbonaceous material of the support structure. Described also is a catalyst system for oxidising CO or hydrocarbons, containing: (a) composite carrier, which contains agglomerates of titanium dioxide nanoparticles, deposited on the carbonaceous material of the support structure, (b) catalytically active gold, deposited on a composite carrier, where said agglomerates are nanoporous, and a method of catalytic oxidation of CO or hydrocarbons, wherein oxidation takes place using the above mentioned heterogeneous catalyst system. ^ EFFECT: increased activity of catalyst systems during catalytic oxidation of CO or hydrocarbons. ^ 8 cl, 1 tbl, 14 dwg, 9 ex |
