Abstract
A supported catalyst is made by preparing a dispersion, contacting the dispersion with a substrate to produce a coating thereon, and firing and, if necessary, reducing to convert the dispersion to a catalytically active coating on the substrate. The catalyst may be useful in the catalysis of reactions for producing methane. The dispersion is made by co-hydrolysis to give an intimate mixture of hydrolysis products (e.g. hydroxides of Ni and Al) convertible by calcining and, if necessary, reduction to produce the catalytically active coating in the form of one or more catalytically active components (e.g. Ni) and one or more ceramic oxides (e.g. Al.sub.2 O.sub.3). Preferably, co-hydrolysis if effected by an agent such as urea which gives rise to no by-products in the coating.
