  Catalysts of carbon monoxide oxidation were synthesized by deposition of
platinum on titanium nitride (TiN). Two substrates with an average particle
size of 18 and 36 nm were obtained by hydrogen reduction of titanium
tetrachloride in a stream of microwave plasma of nitrogen. The surface of the
catalysts was studied by X-ray photoelectron spectroscopy (XPS). The CO
oxidation rate on the 9-15 wt.% Pt loaded TiN catalysts was found to be 120
times higher than that on platinum black with a specific surface of 30 m2/g.
Such catalysts are promising for use in catalytic air purification systems.
