Method of preparing platinum alloy electrode catalyst for direct methanol fuel cell using anhydrous metal chloride
A method for preparing a platinum alloy electrode catalyst for DMFC using anhydrous metal chlorides. The method includes reducing platinum chloride and non-aqueous second metal chloride with boron lithium hydride (LiBH4) in a water-incompatible organic solvent in a nitrogen atmosphere to form nano-sized particles of colloidal platinum alloy, and drying the platinum alloy particles without any heat treatment. The method of preparing a platinum alloy catalyst according to the present invention makes it possible to prepare platinum alloy particles having a narrow range of size distribution and an average particle size of less than 2 nm with ease, relative to the conventional methods. The platinum alloy particles thus obtained can be used as an electrode catalyst for DMFC to enhance methanol oxidation performance.
