Abstract
A catalyst for exhaust gas purification includes a carrier and a platinum group element supported on the carrier. The carrier includes a modified aluminum borate which contains an aluminum borate and at least one of oxides of an element selected from the group consisting of Zr, Si, Fe, and Ti. The modified aluminum borate contains the oxide in a concentration of 0.06% to 18% by mass relative to the mass of the modified aluminum borate.
