Economic considerations require that platinum metals and alloys used as catalysts should have a high surface to volume ratio, thus extremely small particles are required. This article describes a tribophysical process for producing such particles uniformly dispersed on alumina. The catalytic activity and life of the materials produced have been tested for the oxidation of hydrocarbon gas and the results are discussed.
