摘要： A method of preparing a supported catalyst includes dissolving a cation exchange polymer in alcohol to prepare a solution containing cation exchange polymer; mixing the cation exchange polymer containing solution with a catalytic metal precursor or a solution containing catalytic metal precursor; heating the mixture after adjusting its pH to a predetermined range; adding a reducing agent to the resultant and stirring the solution to reduce the catalytic metal precursor; mixing the resultant with a catalyst support; adding a precipitating agent to the resultant to form precipitates; and filtering and drying the precipitates. The method of preparing a supported catalyst can provide a highly dispersed supported catalyst containing catalytic metal particles with a reduced average size regardless of the type of catalyst support, which provides better catalytic activity than conventional catalysts at the same loading amount of catalytic metal.

摘要： 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.

摘要： A method of preparing a supported catalyst, the method comprising mixing a first catalytic metal precursor and a first solvent to obtain a first catalytic metal precursor mixture; mixing a carbon support for catalyst and the first catalytic metal precursor mixture, and drying the mixture to obtain a primary supported catalyst precursor; subjecting the primary supported catalyst precursor to a hydrogen reduction heat treatment, to obtain a primary supported catalyst; mixing the primary supported catalyst and a polyhydric alcohol to obtain a primary supported catalyst mixture; mixing a second catalytic metal precursor and a second solvent to obtain a second catalytic metal precursor mixture; mixing the primary supported catalyst mixture and the second catalytic metal precursor mixture to obtain a secondary supported catalyst precursor mixture; and adjusting the pH of the secondary supported catalyst precursor mixture, and then heating the secondary supported catalyst precursor mixture to obtain a supported catalyst, a supported catalyst prepared by the method, an electrode comprising the supported catalyst, and a fuel cell including the electrode are provided. A supported catalyst having a desired amount of loaded catalytic metal particles can be obtained by preparing a primary supported catalyst containing catalytic metal particles that are obtained by a primary gas phase reduction reaction of a portion of the final loading amount of catalytic metal, and reducing the remaining portion of the catalytic metal by a secondary liquid phase reduction reaction. The supported catalyst contains catalytic metal particles having a very small average particle size, which are uniformly distributed on a carbon support at a high concentration, and thus exhibits maximal catalyst activity. A fuel cell produced using the supported catalyst has improved efficiency.
