发明名称 Exhaust gas purifying catalyst
摘要 An exhaust gas purifying catalyst includes: a support that contains at least one element that is selected from the first group that consists of Al, Zr and Ce, at least one element that is selected from the second group that consists of Ag, Mn, Co, Cu and Fe, and Ti; and particles that are composed of a metal or oxide of at least one element that is selected from the third group that consists of Ag, Mn, Co, Cu and Fe and that are deposited on the support. Seventy percent or more of any plurality of measurement points with a diameter of 2 nm on a surface of the support are composed of a composite part that has the at least one element selected from the second group content of 0.5 to 10 mol % and has a Ti content of 0.3 mol % or greater.
