Title:
HIGHLY HEAT-RESISTANT COMPOSITE OXIDE CATALYST FOR EXHAUST GAS CLEANING, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2018/051890
Kind Code:
A1
Abstract:
The present invention provides a highly heat-resistant composite oxide catalyst for exhaust gas cleaning, which is represented by formula (I): M/M1M2 1-xTixO3-d (In the formula, M denotes at least one type of noble metal selected from the group consisting of Pd, Rh and Pt. M1 denotes Ca, Sr or Ba. M2 denotes Fe, Mn, Co, Ni or Cu. x is 0.4-1.0. d is 0-0.5. M1M2 1-xTixO3-d is a perovskite type metal composite oxide carrier.).
