ABSTRACT OF THE DISCLOSURE A method of preparing a supported catalyst which comprises: 1. sputtering a material which is catalytic, or which is a component of a catalytic system on to the surface of particles which are compatible with the material, and 2. consolidating the thus sputtered particles into aggregated form. This method reduces or avoids certain disadvantages of conventionally prepared catalysts in which some of the metal can be trapped in deep pores in the conventional catalyst particle and thereby be unavail- able for catalysis or induce poor selectivity in the catalysed reaction. The method is applicable to a wider range of substrates that is appropriate to conventional catalysts such as are loaded, for example by impregnation techniques. The catalysts may be used in a wide range of applications. Some examples of such applications are in various hydrocarbon conversion processes, for example naphtha reforming, isomerisation processes, hydrogenation processes, treatment of gaseous effluents and car exhaust treatment systems.
