Description
市販の白金触媒を用意しこれにコバルト、マンガンを担持した。使用した白金触媒は、炭素微粉末(比表面積約900m2/g)を担体とする白金担持率46.5質量%の白金触媒を5g(白金換算で2.325g(11.92mmol)用意した。この白金触媒を、塩化コバルト(CoCl2・6H2O)と塩化マンガン(MnCl2・4H2O)をイオン交換水100mLに溶解させた金属塩溶液に浸漬し、マグネティックスターラーにて攪拌した。そして、この溶液に濃度1質量%の水素化ホウ素ナトリウム(SBH)溶液500mLを滴下し攪拌して還元処理し、白金触媒にコバルト、マンガンを担持した。その後、ろ過・洗浄・乾燥した。
触媒金属を担持した触媒について合金化のための熱処理を行った。本実施形態では、100%水素ガス中で熱処理温度を900℃として30分の熱処理を行った。この合金化熱処理によりPt−Co−Mn3元系触媒を製造した。
