- preparation method of binder-free catalytic electrodes for direct carbon fuel cell by using nickel foam and graphene aerogel and catalytic electrodes by using the same method

摘要

The present invention relates to a method for preparing a binder-free catalyst electrode for a direct carbon fuel cell using a nickel foam and a graphene airgel, and more particularly, (1) (2) preparing a mixed dispersion of graphene oxide containing the active metal ion by adding and stirring a precursor of an active metal for an electrode catalyst to the graphene oxide dispersion; (3) preparing a nickel foam on which the mixed dispersion is supported by adding a nickel foam to the mixed dispersion, stirring and standing the mixture; (4) reacting the mixed dispersion-supported nickel foam with a reducing agent to prepare a nickel foam electrode on which an active metal-supported graphene hydrogel is deposited; And (5) washing and drying the prepared electrode to prepare a nickel foam electrode on which the active metal-supported graphene aerogels are deposited. The binder-free catalyst electrode for a direct carbon fuel cell according to claim 1, And a method for producing the same.
