ABSTRACT:
A highly dispersed supported transition metal catalyst is provided having an ability to withstand highly elevated temperatures and caustic solutions. The transition metal is distributed over the surface of a particulate BBB type polymer of unusually high surface area. The supported catalyst may be formed through the formation of a coordination complex between a transition metal salt and benzimidazonitrogen groups present upon the surface of BBB type polymer, and the subsequent reduction of the metal cations of the salt to the metallic form. The resulting supported catalyst may be utilized in a reaction zone provided at a temperature up to about 500.degree.C., and particularly is suited for use in hydrogenation reactions, isomerization reactions, and oxidation reactions or in a fuel cell application wherein oxygen and hydrogen react to generate electrical current.
