Abstract: A catalyst for clarifying an exhaust gas containing an Al oxide and Pd carried thereon, characterized in that the Al oxide is an LnAlO3(Ln: a rare earth metal); and a method for producing the catalyat. The catalyst for clarifying an exhaust gas exhibits satisfactory clarification performance also in the low temperature operation during idling (400°C or lower).

Abstract: An exhaust gas clarifying catalyst which has an Al oxide and, carried thereon, a Pd oxide, characterized in that the Al oxide is LnAlO3 [wherein Ln represents a rare earth element]. The exhaust gas clarifying catalyst has a noble metal itself exhibiting enhanced activity as compared to the metal contained in a conventional catalyst, and also can prevent its catalytic activity from being lowered by the exposure to a high temperature, which results in the exhibition of satisfactory catalyst performance also in the operation at the start-up and in a low temperature operation (at 400°C or lower).
Abstract translation: 一种废气澄清催化剂，其具有Al氧化物并在其上承载Pd氧化物，其特征在于，所述Al氧化物为LnAlO 3 [其中Ln表示稀土元素]。 废气澄清催化剂具有与常规催化剂中所含的金属相比具有增强的活性的贵金属本身，并且还可以通过暴露于高温来防止其催化活性降低，这导致令人满意的催化剂的展示 在启动和低温操作（400℃或更低）的操作中也具有性能。
