摘　　要：在室温下,通过乙酰胺和无水氯化铝的混合反应制备了新型离子液体。循环伏安测试表明,铝可以顺利从该体系中沉积析出。反应可逆性较好,过程受离子扩散控制。温度和电流密度对铝的形貌影响较大,晶体在电极上的生长以(200)方向为主。该方法操作简单,体系稳定性好,电流效率较高。Acetamide-based ionic liquid was synthesized by mixing acetamide and anhydrous aluminum chloride at room temperature. The results of cyclic voltammograms show that aluminum could be electrodeposited from this ionic liquid. Electrodeposition process is quasi-reversible and mainly influenced by mass diffusion and kinetic limitations. Temperature and current density has significant influence on surface morphology of aluminum. The preferred crystallographic orientation of crystals is （200） on electrode. Compared with traditional methods, this process has advantages of easy operation, high chemical stability, and high efficiency.
