Abstract

1378161 Exhaust gas treatment catalysts IMPERIAL CHEMICAL INDUSTRIES Ltd 2 Feb 1972 [10 Feb 1971] 4370/71 Heading B1E [Also in Division F1] A catalyst comprises a support material plated with a metal in the form of a layer deposited as the metal, e.g. by spraying or from solution by electro-plating or chemical reduction plating. In examples ceramic supports are coated with Ni or Co by immersion in a metal salt followed by reduction in a solution of sodium borohydride and then electro-plating with the metal.
