| 摘 要： | 以羧基化的多壁碳纳米管(C-MWNT)为电催化材料制成了粉末微电极(C-MWNT-PME),采用循环伏安等方法研究了C-MWNT-PME对间硝基甲苯的电还原行为.实验结果表明:C-MWNT-PME对间硝基甲苯具有良好的电催化活性;C-MWNT-PME上间硝基甲苯的电还原反应为一受吸附控制的不可逆过程.在实验基础上,进一步分析研究了C-MWNT-PME在间硝基甲苯电还原过程中的稳定性,结果表明,酸性溶液中C-MWNT-PME在间硝基甲苯电还原过程中是稳定的.

| Abstract: | Powder microelectrode(C-MWNT-PME) was made using multi-walled carbon nanotube functionalized by carboxyl(C-MWNTs) as catalytic materials.Electrochemical reduction behavior of m-nitrotoluene in acid solution on the C-MWNT-PME was investigated by cyclic voltammetery.The results show that the catalytic activity of C-MWNTs for the electroreduction of m-nitrotoluene is good;the electrochemical reduction of m-nitrotoluene on C-MWNTs is an irreversible cathodic wave,which is controlled by adsorption.The stability of the C-MWNT-PME during the process of the electroreduction of m-nitrotoluene was investigated,and the results show that it owns good stability during the process of the electroreduction of m-nitrotoluene in acid solution. |
