Title:
(METAL OXIDE)-PLATINUM COMPOSITE CATALYST, AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/061941
Kind Code:
A1
Abstract:
Disclosed is a catalyst which does not undergo the oxidative corrosion of a carrier contained therein and exhibits a high catalytic activity.
Specifically disclosed is a (metal oxide)-platinum composite catalyst comprising 5 to 95 parts by weight of a metal oxide and 95 to 5 parts by weight of platinum as a remainder, wherein platinum is so arranged as to juncturally cover a part of the surface of each particle of the metal oxide dendritically or lamellarly and has a crystallite diameter of 10 nm or more.
