NOVELTY - Anionic surfactant and carrier are dissolved in polyatomic alcohol, ultrasonically treated, and stirred to obtain mixture (A). Carrier is Vulcan XC-72 (RTM: carbon black), carbon nanotubes, mesoporous carbon or carbon fiber. Metal salt and coordination compound are added into obtained mixture (A) to obtain mixed solution (B). Metal salt is palladium chloride, platinum chloride, gold(III)chloride, silver nitrate, iridium chloride, or rhodium chloride. The obtained mixed solution (B) is heated, washed and dried to obtain supported-type binary alloy catalyst.    USE - Manufacture of supported-type binary alloy catalyst used for direct alcohol fuel cell.    ADVANTAGE - The method efficiently and economically provides supported-type binary alloy catalyst having excellent antitoxic property, activity, and stability.    DETAILED DESCRIPTION - Anionic surfactant and carrier are dissolved in polyatomic alcohol, ultrasonically treated, and mechanically stirred to obtain uniform mixture (A). The concentration of anionic surfactant in the mixture is 0.5-3 times with respect to critical micelle concentration. The carrier is Vulcan XC-72 (RTM: carbon black), carbon nanotubes, mesoporous carbon or carbon fiber. The anionic surfactant is stearic acid, oleic acid, lauric acid, lauryl sodium sulfate, sodium lauryl sulfate, and/or 4-dodecylbenzenesulfonic acid. Metal salt and coordination compound are added into obtained mixture (A) to obtain mixed solution (B), such that total content of metal element in metal salt and coordination compound is 20-60%. The metal salt is palladium chloride, platinum chloride, gold(III)chloride, silver nitrate, iridium chloride, or rhodium chloride. The coordination compound is disodium hexachloroplatinate, sodium hexachloro palladate, potassium hexachloroplatinate, dihydrogentetrachloropalladate, chloroauric acid, hexachloroiridium acid hydrate, chloroplatinic acid hexahydrate, potassium tetrachloropalladate, potassium tetrachloroaurate(III), sodium tetrachloroaurate(III), iridic sodium chloride or dipotassium hexachloroiridate. The atomic ratio of metal elements in metal salt with respect to metal elements in the coordination compound is 1:0.2-5. The obtained mixed solution (B) is heated in microwave at 80-160 degrees C, washed and dried to obtain supported-type binary alloy catalyst.
