PROBLEM TO BE SOLVED: To provide a simple method for producing a crystalline platinum particle with a large size. SOLUTION: The method is characterized in that a platinum complex compound, acid, 2C-12C primary alcohol and aliphatic primary amine are contacted with each other in an organic solvent. The crystalline platinum particle produced by the method has a large size, and, preferably, is a single crystal platinum cube to which a specific face is substantially exclusively exposed. Thus, the platinum particle can be suitably used for an electrode material, a catalyst in chemical reaction, the electrocatalyst of a fuel cell or the like. COPYRIGHT: (C)2011,JPO&INPIT |
