OXYGEN-DONOR AND CATALYTIC COATINGS OF METAL OXIDES AND METALS

摘要

A method to fabricate thin, penetrating coatings of metal oxides with oxygen storage capability is disclosed. The application of these coating in diesel exhaust particulate oxidation, carbonization prevention in ethylene cracking pipes etc. is also disclosed. In this method, the use of thin, penetrating coatings of catalytic metals decreases the oxidation temperature of carbon in contact with or near the coated surfaces. Finally, the invention describes a method to prepare a better bonding surface for laying down catalysts through traditional calcification slurry methods, by pre-coating the surface with a thin, penetrating coating of metal oxide.
