aplicação de troca básica de materiais para baixar a temperatura da oxidação catalítica de particulados

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.
