CARRIER FOR EXHAUST GAS PURIFYING CATALYSTS, EXHAUST GAS PURIFYING CATALYST AND METHOD FOR PRODUCING SAME

摘要

A carrier which contains an La2O3-modified aluminum borate having a specific composition, said La2O3-modified aluminum borate being obtained by modifying aluminum borate that contains aluminum oxide and boron oxide at a ratio of from 10:2 to 9:2 with La2O3 so that the amount of La2O3 based on the mass of the aluminum borate is 0.3-2% by mass. An exhaust gas purifying catalyst which contains the carrier and Pd or Pd + Ba that are supported by the carrier. A catalyst configuration which contains a catalyst supporting body that is formed of a ceramic or a metal material and a layer of the exhaust gas purifying catalyst, said layer being disposed on the catalyst supporting body. The catalyst configuration may additionally contain an Rh catalyst layer that is disposed on the layer of the exhaust gas purifying catalyst. A method for producing an exhaust gas purifying catalyst.
