Abstract
Description
八面体Pt−Cu−Ni/Cサンプルは、C担体(Vulcan XC 72)上に金属前駆体を含浸させ、COおよびH2混合ガス中でそれらを還元することを含む、拡張性があり、界面活性剤を用いない、簡便で革新的な固体化学法を用いて調製した。具体的な手順として、カーボンブラック(バルカンXC−72)は、使用前に水分を除去するために一晩300℃の空気中で熱処理した。プラチナ(II)アセチルアセトネート、銅(II)アセチルアセトネート、およびニッケル(II)アセチルアセトネートは、2:1:1(Pt:Cu:Ni)のモル比でアセトンに溶解し、最終的なPt濃度が20重量%となるように前処理されたC担体に滴下し、激しく撹拌した。混合物は、真空チャンバ内に1時間保持し、残留アセトンを完全に除去した。乾燥混合物は、H2/CO(5/120cm3/min)のガス雰囲気下、5℃/minで最終温度が200℃になるまで昇温し、200℃で1時間保持することによって還元した。混合物は、H2/COガス雰囲気下で周囲温度まで降温した。周囲温度に到達後、製品を回収する前に系内を清めるためにガスをアルゴンに切り替えた。
MTBD(3.00g、0.0196mol)を水(100mL)に溶かした水溶液を0℃まで冷却し、それに硝酸(1.76g、0.0196mol)を滴下した。次いで、ノナフルオロブタンスルホン酸カリウム(8.58g、0.0196mol)を水溶液に添加し、1時間撹拌した。得られたイオン液体は水相の下に粘性液相となって分離した。
それを超純水で4回洗浄した。洗浄後のイオン液体を減圧下、50℃で18時間にわたり乾燥させ、融点が45℃程度の白色物質を得た。
5mg/mLの[MTBD][C4F9SO3]を含むイソプロパノールを調製した。小瓶にPt−Ni−Cu/C触媒を入れ、初めに0.5mLの脱イオン水で濡らし、次いでIL/C重量比を0、1.28、2.56、3.84に変化させて所望のイオン液体ストック溶液を添加した。混合物に対し20分間超音波処理を行い、溶媒を45℃雰囲気下でゆっくり取り除いた。最後に、得られた粉末を高真空下(−1バール、室温)で一晩さらに乾燥させた。
実施例3で得られた10mgの製品粉末を、6mLの脱イオン水、4mLのイソプロパノール、および40μLのナフィオン(登録商標)アイオノマー(Nafion DE 520)と混合した。この混合物は、15分間バス超音波処理し、次に1分間プローブ超音波処理し、触媒インクを製造した。10μLの触媒インクを研磨して洗浄されたガラス状炭素電極(直径5mm)上に配置した。当該電極を電極回転子(パインリサーチインスツルメンテーション社製)に取り付け、400rpmで回転させた。
電気化学的測定はすべてパインインスツルメンテーション社製のRDEワークステーションを用いて行った。実施例3で得られた触媒を被覆したガラス状炭素作用極、白金ワイヤー対極、およびハイドロフレックス(登録商標)参照電極(ET070、eDAQ社製)からなる3極システムを全ての電気化学測定で使用した。電解質(0.1M HClO4)は、測定毎に新たに調製した。
