Catalyst carrier, catalyst, and method for producing catalyst carrier and catalyst

The purpose of the present invention is to provide: a catalyst carrier having both periodic mesopores and heat resistance; a catalyst; and methods for producing the catalyst carrier and the catalyst. A catalyst carrier (1) according to the present invention comprises: porous silica particles (2) having a plurality of mesopores (4) having a peak pore diameter of 2-50 nm as analyzed by the BJH method, the plurality of mesopores (4) forming a periodic structure; and metal oxide particles (3) containing at least one element selected from the group consisting of Al, Ti, Mg, Zr, Fe, Ce, and Si. The metal oxide particles (3) are present in at least voids (5) between the porous silica particles (2). 本发明的目的在于提供一种既具有周期性介孔又具有耐热性的催化剂载体、催化剂及它们的制造方法。本发明的催化剂载体(1)包含：多孔质二氧化硅粒子(2)，具有利用BJH法所解析的峰细孔径为2～50nm的多个介孔(4)，且多个介孔(4)形成周期结构；及金属氧化物粒子(3)，包含选自Al、Ti、Mg、Zr、Fe、Ce及Si的群中的至少1种元素；且金属氧化物粒子(3)存在于多孔质二氧化硅粒子(2)之间的至少空隙(5)中。
