Nano-composite of AI2O3 and Soiid Solution as a Support for NOx Storage-reduction Catalyst

摘要

A nano-composite of AI2O3 and ZrO2"TiO2 solid solution (ZT) was synthesized and characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). After heat durability test, the particle average size of ZT in the nano-composite of AI2O3 and ZT was small relative to that in the physically mixed AI2O3 and ZT. The catalyst containing nano-composite of AI2O3 and ZT promoted desorption of sulfur than the catalyst containing the physically mixed AI2O3 and ZT.
