Abstract
Official abstract text for this publication.
Provide is a new carrier for exhaust gas purification catalyst which exhibits excellent catalytic activity, particularly catalytic activity at a low temperature. Proposed is a carrier for exhaust gas purification catalyst composed of particles which contain a silicate or phosphate containing one kind or two or more kinds among the elements belonging to Group 1 and Group 2 in the periodic table.
First claim
Opening claim text (preview).
The invention claimed is: 1. A carrier for exhaust gas purification catalyst comprising particles containing a silicate containing one kind or two or more kinds among elements belonging to Group 1 and Group 2 in the periodic table, wherein the silicate is A 2 SiO 4 (A is an element including Sr or Ba or these two kinds), ASiO 3 (A is an element including Sr or Ba or these two kinds), or a mixture of these. 2. The carrier for exhaust gas purification catalyst according to claim 1 , wherein the silicate is a silicate containing Ba. 3. An exhaust gas purification catalyst comprising the carrier for exhaust gas purification catalyst according to claim 2 and a catalytically active component. 4. An exhaust gas purification catalyst comprising the carrier for exhaust gas purification catalyst according to claim 1 and a catalytically active component. 5. A carrier for exhaust gas purification catalyst comprising particles containing a phosphate containing one kind or two or more kinds among elements belonging to Group 1 and Group 2 in the periodic table, wherein the phosphate is A x PO 4 (x=2 or 1.5, A in the case of x=2 is a combination of any one kind of monovalent element or two or more kinds of monovalent elements among Li, Na, K, and Cs with any one kind of divalent element or two or more kinds of divalent elements among Mg, Ca, Sr, and Ba, A in the case of x=1.5 is two or more kinds of divalent elements among Mg, Ca, Sr, and Ba or divalent element comprising Sr). 6. The carrier for exhaust gas purification catalyst according to claim 5 , wherein the phosphate is a phosphate containing Ba. 7. An exhaust gas purification catalyst comprising the carrier for exhaust gas purification catalyst according to claim 5 and a catalytically active component.
