Title:
酸化触媒及びディーゼルパーティキュレートフィルター
Document Type and Number:
Japanese Patent JP5773337
Kind Code:
B2
Abstract:
Provided are a layered complex oxide that can lower PM oxidation temperature and increase oxidation rate, and a nitrogen oxides reduction catalyst, a three-way catalyst, a DPF and an oxidation catalyst, each of which includes the layered complex oxide. The layered complex oxide has a layered perovskite structure and has a composition represented by the formula: (Ln 3-X A X ) 1-± Mn 2 O 7-´ (wherein Ln is La and/or Nd, A is Sr and/or Ca, a is degree of A-site deficiency, ´ is the oxygen deficit amount, and X, ´ and ± satisfy 0< X< 3, 0<±< 1 and ´< 1.4), which are included in the catalysts and DPF.
