  • Exhaust gas purifying catalyst
    Patent number: 5462905
    Abstract: An exhaust gas purifying catalyst is characterized in that at least one kind of catalyst metal is loaded on a layered porous silica or a layered porous silica-metal oxide. The exhaust gas purifying catalyst is used as an oxidation catalyst for purifying hydrocarbon and carbon monoxide, or a reduction catalyst for purifying nitrogen oxides (NO.sub.x), which is suitable for purifying exhaust gases in automobiles. An exhaust gas purifying apparatus includes the above exhaust gas purifying catalyst and an absorbent for trapping hydrocarbon components, in which aromatic HC such as trimethylbenzene and the like are effectively trapped.
