(ZA9505088-A)      An oxidn. catalyst comprises a porous alumina support, as pellets or powder, which has captured thereon a complex of gold, alumina and a transition metal comprising cobalt or manganese; the gold concn. is less than 2 wt.% of the catalyst and the gold to transition metal atomic ratio is 1:10-200.    USE -    The catalyst oxidises CO and hydrocarbons and is useful in motor vehicle exhausts, gas masks, air purificn. in mines, purificn. of industrial effluents, and for recycling CO2in lasers and fuel cells.
