LAYERED COMPLEX OXIDE, OXIDATION CATALYST AND DIESEL PARTICULATE FILTER
Document Type and Number:
WIPO Patent Application WO/2012/147583
Kind Code:
A1
Abstract:
Provided are a layered complex oxide which can lower PM oxidation temperature and increase oxidation speed, and a nitrogen oxide purification catalyst, a three-way catalyst, a DPF, and an oxidation catalyst using such a layered complex oxide. A layered complex oxide having a layered perovskite structure and a composition represented by the formula: (Ln3-XAX)1-αMn2O7-δ (in the formula, Ln represents La and/or Nd, A represents Sr and/or Ca, α represents the A-site deficit amount, δ represents the oxygen deficit amount, and X satisfies the relationship 0
