Title:
METHOD FOR CARRYING METAL ON GRAPHENE OXIDE AND METAL-GRAPHENE OXIDE COMPOSITE CREATED WITH SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2014/042259
Kind Code:
A1
Abstract:
Provided are: a method for carrying a metal on graphene oxide, in which a desired metal is carried on graphene oxide while suppressing the occurrence of graphene aggregation in a graphene oxide dispersion in which graphene oxide is dispersed; and a metal-graphene oxide composite created with this method. A solution containing a metal salt or metal ions is added to a graphene oxide dispersion solution in which graphene oxide is dispersed. At least one of alcohol (except tertiary alcohols), N,N-dimethylformamide, tetrahydrofuran, and 1,4-dioxane is added as a reducing agent. The reducing action of the reducing agent causes the graphene oxide to carry the metal of the metal salt or metal that has become the metal ions.
