Title:
METHOD FOR PRODUCING MANGANESE OXIDE NANOPARTICLE DISPERSED MATERIAL AND ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2007/072739
Kind Code:
A1
Abstract:
Disclosed is a method for producing a manganese oxide dispersed material which enables to miniaturize the size of manganese oxide and to uniformly disperse the manganese oxide in a carrier. Specifically disclosed is a method for producing a manganese oxide nanoparticle dispersed material, which comprises a step 1 wherein manganese nitrate is dissolved into a polyamide acid solution, a step 2 wherein a coating film composed of the polyamide solution in which the manganese nitrate is dissolved is formed on the surface of a base, and a step 3 wherein the polyamide acid is carbonized while depositing manganese oxide nanoparticles by heating the coating film at a temperature not less than 600˚C but not more than 1200˚C.
