采用含钴盐的高孔聚丙烯腈微孔泡沫制备钴碳化气凝胶纳米复合材料。用旋转圆盘电极法研究了氧在该材料上的电化学还原。在接近燃料电池阴极的实验条件下，即在酸性溶液中催化剂/Nafion®界面处，证明了该材料具有良好的氧还原电催化活性。
Cobalt-carbonized aerogel nanocomposite was prepared from highly porous polyacrylonitrile microcellular foams containing a salt of cobalt, followed by carbonization. The electrochemical reduction of oxygen was studied at this material by using the rotating disk electrode method. Good electrocatalytic activity for oxygen reduction at this material was demonstrated under experimental conditions close to those of a fuel cell cathode, that is, at the catalyst/Nafion®interface in acidic solutions.
