Description
はじめに、図2を用いて、カーボンナノウォール2aから金属を担持させるナノグラファイトを生成する処理(ステップ1)の一例について説明する。このカーボンナノウォール2aは、シリコン(Si)基板1等の基板上にプラズマCVD等の方法で生成することができる。シリコン基板1には、複数のカーボンナノウォール2aが密集して配置されている。
次に、カーボンナノウォール片が分散する液体に担持させる金属を混合する処理(ステップ2)の一例について説明する。まず、ステップ1の処理で得られたナノグラファイトを、蒸留水等の液体に分散させる。その後、カーボンナノウォール片が分散される液体中に、白金前駆体等の金属を混合させる。
続いて、カーボンナノウォール片に金属を担持させる処理(ステップ3)について説明する。ここでは、カーボンナノウォール片及び金属を含む液体に還元剤を注入し、カーボンナノウォール片に白金を担持させる。例えば、還元剤としては、ホルムアルデヒドを利用することができる。
続いて、10×10cm2のシリコン基板上に生成したカーボンナノウォールを用いてカーボンナノウォール片を生成した実施例について説明する。ここで、基板温度約500℃、放電電流70A、ガス流量Ar:80sccm,H2:10sccm,CH4:10sccm、反応時圧力3.0×10-3Torr、反応時間360minの条件下での生成が3回繰り返され、合計約100mgのカーボンナノウォールが得られた場合を例に説明する。
