摘　　要：合成、表征了两种典型的氯铝酸离子液体,1-丁基-3-甲基咪唑氯铝酸盐和1-烯丙基-3-甲基咪唑氯铝酸盐。在此基础上,通过电化学测试和原子力显微镜对铝在离子液体中的电沉积规律进行了系统研究,证明反应过程受离子扩散控制,可逆性较好,可获得微纳米铝。离子液体的阳离子结构对产物的状态和尺寸影响较大,降低离子间相互作用能可以进一步获得更加细致、平整的铝晶体。Two typical chloroaluminate ionic liquids, and 1-allyl-methylimidazolium chloroaluminate including 1-butyl-methylimidazolium chloroaluminate were synthesized and characterized. Systematic measurements based on electrochemistry and atomic force microscope were conducted to explore electrodeposition behavior of aluminum in ionic liquids. Experimental results show that deposition process is quasi-reversible and controlled by ion diffusion. Micro-nano aluminum can be electrodeposited by this method. Structure of cation has significant effect on shape and size of aluminum deposits. Smoother and finer aluminum crystals can be obtained in ionic liquids with lower interaction energy among cations and anions.
