| 摘 要： | 采用表面修饰和原位还原碳化技术制备了碳化钨（WC）/碳纳米管（CNT）纳米复合材料，并以其为电催化剂制成了WC/CNT纳米复合材料粉末微电极（WC/CNT-PME）。采用计时电流法、循环伏安法和原位红外反射光谱技术研究了酸性溶液中硝基苯在WC/CNT-PME上的电化学行为，讨论了扫描速率和温度对其电化学行为的影响。结果表明，WC/CNT纳米复合材料对硝基苯的电催化活性明显高于碳纳米管和纳米碳化钨;硝基苯在WC/CNT-PME上的还原反应是一受吸附控制的不可逆过程，其还原产物为对氨基苯酚。

| Abstract: | WC/carbon nanotube(CNT)nanocomposite was prepared by surface decoration and in situ reduction technique and subsequently was used as an electrocatalyst to prepare the WC/CNT powder microelectrode(WC/CNT-PME).Electrochemical reduction behavior of nitrobenzene on the WC/CNTPME was investigated by chronoamperometry and cyclic voltammetry,combined with in situ FTIR,the influences of scan rate and temperature on the electroreduction behavior of nitrobenzene were discussed. Results showed that WC/CNT nanocomposit... |
