Catalyst including anodized aluminum substrate and method of manufacture.

摘要

The invention concerns a heterogeneous catalyst produced by etching an aluminum substrate (10) to form macropores (11) therein, anodizing the etching substrate to establish a microporous aluminum oxide film (12) on the walls of the macropores, and depositing at least one catalytically active metal (16) in the micropores of the oxide film, e.g. by an electro-deposition technique. The calayst has a high surface area of active components and a high activity per unit weight of catalyst. The catalyst can be used for a variety of purposes, depending on the active metal deposited, e.g. petroleum refining, chemical processing and emission control.
