ABSTRACT:
Catalysts for use in promoting heterogeneous chemical reactions, such as hydrogenation, cracking, dehydrogenation and Fischer-Tropsch reactions, are prepared by depositing a catalytically active metal such as nickel electrolytically onto an aluminum substrate in such a manner that the metal particles are deposited in micro-particulate form to enhance their catalytic activity. The aluminum substrate is prepared by cleaning and anodizing it, so as to deposit thereon an aluminum oxide surface film having micro porosity. Then the substrate is immersed into an electrolysis bath of solution of salt of the metal to be deposited, and subjected to alternating current electrolysis to cause the required deposition. Prior to use, the catalysts so prepared should be heated to remove absorbed gases from their porous surfaces.
