Description
炭素ナノフォーム紙は、市販のものを購入するか、または自作した。MnO2−炭素ナノアーキテクチャーハイブリッドは、水溶液中の過マンガン酸塩の還元分解に基づいて作製した。この炭素ナノアーキテクチャー表面を、水溶性過マンガン酸塩を不溶性MnO2に変換する犠牲還元体として作用させることができる。
前記MnO2−炭素ナノフォーム電極を、電気化学分析のため1M Na2SO4により減圧下で湿らせ、サイクリックボルタンメトリー、インピーダンス分光法、および定電流充放電測定などの技術を使って、従来の3電極電気化学セル(電気化学電池)で特徴付けた。炭素エアロゲルだけの電極、ならびにそれぞれ4時間酸性析出および4時間中性析出させたMnO2−炭素ナノフォーム電極の、1M Na2SO4中、2および20mVs−1での代表的なサイクリックボルタモグラムを、図5に示す。
** ナノフォーム電極面の幾何学的面積で正規化した。
