Abstract
PURPOSE: To obtain the title catalyst uniformly supporting platinum fine powder and having high activity in a low temp. zone by dissolving dinitrodiaminoplatinum powder in an aq. nitric acid soln. under specified conditions; aging the soln.; impregnating an activated alumina carrier with the aged soln.; and resucing the impregnated carrier.
CONSTITUTION: (NH3)2(NO2)2Pt powder is added to a 250W450g/l aq. nitric acid soln. and dissolved by heating to 60W100°C to prepare a soln. contg. 250W 450g/l of Pt. By aging the soln. at 60W100°C for an adequate time the color of the soln. is turned dark reddish brown. An activated alumina carrier is dipped in the aged soln. to well impregnate the carrier with the platinum cpd., and the impregnated carrier is reduced to obtain a catalyst with platinum fine powder uniformly dispersed. This catalyst is suitable for use in oxidation of CO gas in exhaust gas from an internal combustion engine, etc.
