摘要:
本文将1-乙基-3-甲基咪唑醋酸盐离子液体修饰在多壁碳纳米管上,制备出离子液体/碳纳米管复合材料,并研究了对甲氧基甲苯(p-MT)在该复合离子液体水溶液体系中的电氧化性能. 同时,通过循环伏安法和计时电流法考查了扫描速率、温度、反应底物浓度等因素对电氧化性能的影响,研究了p-MT在该体系中的动力学过程. 实验结果表明,p-MT在复合离子液体水溶液体系中发生不可逆的电氧化反应,且该过程受扩散控制,扩散系数为7.69×10-10 cm2·s-1. 适当地升高温度和增大反应底物浓度都有利于促进p-MT中C-H键选择性电氧化为相应醛基,选择性可达到95%. 通过在不同结构电解槽中进行恒电位电解研究,发现离子液体/MWCNTs复合电解质在一室型电解槽中进行p-MT电氧化的电解效率更高、对目标产物对甲氧基苯甲醛(p-MBA)的选择性也更好.
