CARBON SUPPORTED PT-IR ALLOY CATALYST AND METHOD FOR SYNTHESIZING THE SAME, ELECTRODE AND FUEL CELL COMPRISING THE CATALYST |
摘要 |
PURPOSE: A carbon supported platinum-iridium alloy catalyst and a method for synthesizing the same, an electrode fuel cell including the catalyst are provided to synthesize platinum-iridium alloy particles in a carbon support at a room temperature by supplying a stabilizer and a reducing agent in a colloidal solution containing a platinum precursor, an iridium precursor, and the carbon support. CONSTITUTION: A carbon supported platinum-iridium alloy catalyst is obtained by supplying a reducing agent in a colloidal solution containing a platinum precursor, an iridium precursor, and a carbon support. The colloidal solution contains a stabilizer. The synthesis of the carbon supported platinum-iridium alloy catalyst is implemented at a room temperature. The solvent of the colloidal solution is ethanol, methanol, or tetrahydrofuran. The stabilizer is an ammonium bromide-based compound represented by chemical formula 1. The pH value of the colloidal solution is between 1 and 11. The stabilizer is eliminated after the carbon supported platinum-iridium catalyst is obtained. |
