PREPARATION METHOD FOR THE DIRECT METHANOL FUEL CELL CATALYSTS WITH PTRU NANOALLOY

摘要

The present invention is by dissolving the platinum precursor, a ruthenium precursor and a reducing agent more specifically relates to a method for manufacturing a direct methanol fuel cell catalysts containing PtRu nano-alloy in a solvent and adding a surface stabilizer after heating under an inert gas atmosphere and refluxed platinum-gaining ruthenium nano-alloy adsorb them to the support platinum-direct methanol fuel cells containing the PtRu nano-alloys comprising the step of removing the surface stabilizer of a ruthenium catalyst of platinum with chemical methods to get the ruthenium catalyst It relates to a process for the preparation of the catalyst. ; The invention PtRu nano alloys to remove surface stabilizer to synthesize a direct methanol fuel cell catalyst, and chemical methods containing colloidal PtRu nano-alloy in a fast, simple way to select an organometallic precursor through the reduction reaction in the surface stabilizer direct an object of providing a manufacturing method of a methanol fuel cell catalyst containing a. ; The present invention includes a direct methanol fuel cell catalyst containing nano PtRu alloy manufactured using the same method as above. ; The present invention includes a direct methanol fuel cell comprising a catalyst containing a nano PtRu alloy manufactured using the same method as above.
