摘　　要：研究了多壁纳米碳管(MWNTs)在碱性电解液中的电化学行为.结果表明:电极集流体结构对其电化学活性有较大影响;循环伏安曲线显示,氢在MWNTs上的电化学反应可逆性随循环次数增加而有一定改善;阴极极化曲线表明了MWNTs不同类型上的氢析出电位有一定差别.认为MWNTs在碱性电解液中氢的电化学反应可逆,氢析出电位与MWNTs类型有关.The electrochemistry behavior of multi-walled carbon nanotubes in alkaline electrolyte was studied by electrochemistry method. The results showed that the electrode current conductor influenced its electrochemistry reaction active of hydrogen; and circular V-A curves showed that the hydrogen reversibility in electrochemistry reaction on the electrode was determinately improved along with the increase of V-A cycle numbers, and cathode polarization curves showed that hydrogen separate potential was different on different types of multi-walled carbon nanotubes. It was consider that electrochemistry reaction of hydrogen was well reversible on multi-walled carbon nanotubes in alkaline electrolyte, and hydrogen separate potential was relevant to different types of multi-walled carbon nanotubes.
