Description
以下、本実施形態にかかる担持触媒について、製造例および実施例を挙げて説明する。なお、本発明は、下記製造例および実施例に限定されるものではない。
まず、触媒金属前駆体H2PtCl6xH2O(umicore社製、Pt含有量39.8wt%)1.4656gをエチレングリコール(EG)10gに溶解して、触媒金属前駆体含有混合物を製造した。次いで、カーボン(KB、SE=800m2/g)0.25gをエチレングリコールと水が混合された溶液267g(EG150g、H2O117g)に入れて、20分間超音波で分散した。そして、金属前駆体混合物とカーボンとが分散された混合物を10分間攪拌した後、反応物を1MのNaOH溶液でpHを11に滴定して再び10分間攪拌した。
参考製造例1の触媒に同量の金属前駆体混合物を入れて、もう1回還元を繰り返すことにより、多層構造の87.5wt%Pt/C触媒を製造することができる。
触媒金属前駆体(H2PtCl6xH2O)1.8844g、EGおよび水が混合された溶液367g(EG210g、H2O157g)を入れて、製造例1と同じ過程により触媒を合成する。得られた触媒から、多層構造の85.7wt%Pt/C触媒を製造することができる。
製造例3の触媒に同量の金属前駆体混合物を入れて、もう1回還元を繰り返すことにより、90wt%Pt/C触媒を製造することができる。
触媒金属前駆体(H2PtCl6xH2O)2.5126g、EGと水が混合された溶液467g(EG267g、H2O200g)を入れて、製造例1と同じ過程により触媒を合成した。得られた触媒から、多層構造の88.9wt%Pt/C触媒を製造することができた。
