Description
この国際特許出願は、「希土類金属を含まないOSMの熱安定性組成物」と題する2013年10月16日に出願された米国特許出願第14/055,411号の優先権を主張し、引用することによってその全体を説明するように本明細書に組み込むものとする。
この開示は、一般に、異なる用途を備えた高い酸素貯蔵容量を有する酸素貯蔵材料、より詳しくは、触媒系用の、白金族金属および希土類金属を含まないOSMの相安定性におけるエージングの効果に関する。
三元触媒(TWC)は、活性サイトとしての白金族金属(PGM)、大きな比表面積を備えたアルミナ系担体、および酸素貯蔵特性を調整する金属酸化物促進材料を含み、一酸化炭素(CO)、未燃焼炭化水素(HC)、および窒素酸化物(NOx)の排出の制御用内燃機関の排気ガスラインに設置されている。
本明細書で使用されるように、次の用語は次の定義を有し得る。
本開示は、本開示における原理にしたがって、向上されたOSCおよび熱的安定性を有し、より多くの活性成分を、向上された酸素可動性および相安定性などの相材料所有特性に組み入れて、ZPGM−ZRE金属OSMが採用され得る触媒系の触媒作用を向上し得るZPGM−ZRE金属OSMに対するエージング温度の効果を概してもたらし得る。
