Abstract:
Zero-PGM (ZPGM) catalyst materials including pseudo-brookite compositions for use in diesel oxidation catalyst (DOC) applications are disclosed. The disclosed doped pseudo-brookite compositions include A-site partially doped pseudo-brookite compositions, such as, Sr-doped and Ce-doped pseudo-brookite compositions, as well as B-site partially doped pseudo-brookite compositions, such as, Fe-doped, Co-doped Ni-doped, and Ti-doped pseudo-brookite compositions. The disclosed doped pseudo-brookite compositions, including calcination at various temperatures, are subjected to a DOC standard light-off (LO) test methodology to assess/verify catalyst activity as well as to determine the effect of the use of a dopant in an A-site cation or a B-site cation within a pseudo-brookite composition. The disclosed doped pseudo-brookite compositions exhibit higher NO oxidation catalyst activities when compared to bulk powder pseudo-brookite, thereby indicating improved thermal stability and catalyst activity when using a dopant in an A-site cation or in a B-site cation within a pseudo-brookite composition.

Claim (Index 14):
The catalyst composition of  claim 13 , wherein the catalyst composition is calcined at a temperature of about 800\u00b0 C.
