The present invention relates to the formation and use of catalytic materials as a part of or in association with heat exchangers such as automotive radiators and air conditioning condensers. The catalytic material involves a metal substrate with a porous anodic oxide coating and metallic nodules which are electrodeposited in the pores and extend above the surface of the anodic oxide coating. The nodules are either formed of the catalytic metal or formed of other metals and then coated with the catalyst metal. The catalytic stock material is then formed into heat exchanger fins and mounted on the heat exchanger tubes. In the alternative, the catalytic stock material may be formed into a separate catalytic structure which is then mounted in an air flow stream and preferably in air-flow relationship to the heat exchanger.
