Description
200mgのSWCNT(NanoAmor)を50mLの脱イオン水に分散させ、2時間(20W)超音波処理することにより懸濁液を製造した。次に懸濁液を丸底フラスコに入れ、50mLの濃HNO3(16M)を加えた。反応ボリュームを120℃で5日間磁気撹拌しながら還流し、次いで室温まで冷却した。反応ボリュームを脱イオン(DI)水で洗浄し、遠心分離して粒子を分離した。中性pHに達するまで洗浄および遠心分離プロセスを繰り返した。
反応ボリュームを加熱した後に、5日間ではなく2時間撹拌する以外は、実施例1のプロセスを繰り返した。
200mgのSWCNT(NanoAmor)を100mLの濃塩酸に分散させ、室温で30分間超音波処理して懸濁液を製造した。懸濁液を2Lの水(0.2μmポリテトラフルオロエチレン膜を使用して減圧下で濾過した脱イオン水)で希釈し、中性pHに達するまで脱イオン水で洗浄した。次いで、濾過した物質を後の使用のために40mLの脱イオン水に分散させた。
ポリオール還元法を使用し、ポリマーコーティングされたパラジウム(Pd)ナノ粒子を合成した。1.5mLの65mM H2PdCl4を5mLの5重量%ポリビニルピロリドン(PVP)のエチレングリコール(EG)溶液と混合し、100mLのEGを加えることによって、反応ボリュームをシュレンク管で調製した。反応ボリュームをアルゴンで飽和させ、その後、減圧下で5回脱気し、溶存酸素を除去した。次いで、500rpmで撹拌しつつ、この脱気した溶液を130℃で3時間加熱し、その後、160℃で1時間加熱することによって、PVPコーティングされたPdナノ粒子を製造した。図7Aは、得られたPVPコーティングされたPdナノ粒子を示す電子顕微鏡写真である。
実施例4のPdナノ粒子溶液を室温まで冷却した後、SWCNTを水に分散させたもの20mLをPdナノ粒子溶液に加えて脱気した後、撹拌しつつ、脱気した溶液を130℃で3時間加熱し、160℃で1時間加熱した。過剰のアセトンをPd-SWCNT溶液に添加し、4000rpmで10分間遠心分離処理し、上澄み溶液を捨て、Pdで装飾されたSWCNT(Pd-SWNT)を取り出した。この粒子をさらに15分間撹拌しながら過剰のエタノールで洗浄し、続いて4000rpmで10分間遠心分離処理し、PVPをPd-SWCNT粒子から除去した。洗浄手順を5回繰り返した。
