APPLICATION OF BASIC EXCHANGE OS MATERIALS FOR LOWER TEMPERATURE CATALYTIC OXIDATION OF PARTICULATES

摘要

Catalysts for the direct catalytic oxidation of diesel particulate matter are disclosed. The catalysts relate to OIC/OS materials having a stable cubic crystal structure, and most especially to promoted OIC/OS wherein the promotion is achieved by the post-synthetic introduction of non- precious metals via a basic (alkaline) exchange process.
