Abstract

The present invention relates to a catalyst carrier comprising an apatite-type composite oxide and proposes a catalyst carrier capable of improving purification performance of NOx due to improvement of phosphorus poisoning. Proposed is a catalyst carrier which contains a composite oxide that is represented by a composition formula of (LaA)BO(wherein, 0.3≦δ≦3.0, 0.0<γ≦6.0; 'A' represents one or two or more elements selected from Ba, Pr, Y, Sr, Mg, and Ce; and 'B' represents one or two or more elements selected from Si, P, and Fe).
