Cerium-zirconium mixed oxide nanostructures for diesel soot oxidation: synthesis and effect of structure.

Nanostructured materials have been used in several branches of science and technology. Particulate matter is one of the major air pollution concerns. In this work, nanorods and nanoparticles of CeZrO (CZ) mixed oxides were prepared by different routes, and the use of an organic template was evaluated in diesel soot oxidation.
