Abstract
Official abstract text for this publication.
According to the present invention, an exhaust gas purifying catalyst is provided. The catalyst comprises a porous silica support comprising silica having a pore structure, and a perovskite-type composite metal oxide particle supported in the pore structure of the porous silica support. Further, the peak attributable to the space between silica primary particles is in the range of 3 to 100 nm in the pore distribution of the porous silica support.
First claim
Opening claim text (preview).
The invention claimed is: 1. An exhaust gas purifying catalyst, wherein the catalyst comprises a porous silica support comprising silica having a pore structure, and a perovskite-type composite metal oxide particle supported in the pore structure of said porous silica support; wherein a peak attributable to a space between silica primary particles is in the range of 5 to 50 nm and a peak attributable to the pore structure of silica is in the range of 1 to 5 nm in the pore distribu…
