摘要
以CuCl2.2H2O和NaOH为原料,离子液体-水混合溶剂为介质,采用溶剂热反应法制备了二维CuO纳米片。在反应过程中,离子液体发挥模板剂的作用,实现了CuO纳米片自组装合成;并且通过反应温度、表面活性剂及1,3-咪唑基离子液体阴离子的改变,实现了CuO纳米晶体形貌的可控合成,讨论了CuO纳米片的形成机理。用XRD、FESEM和TEM/SAED对CuO纳米晶体进行了结构和形貌表征;用FTIR和TG/DSC证实了离子液体修饰在CuO纳米片的表面,从而有效地阻止了CuO纳米片的团聚。离子液体在反应中发挥了助溶剂、模板剂和修饰剂的三重作用。
The 2-D CuO nanoplatelets were synthesized by solvothermal reaction using CuCl2·2H2O and NaOH as raw materials in the mixed solvents of ionic liquids and water.CuO nanoplatelets were prepared based on self-assembly by ionic liquids working as structure-directing agent.Morphology control of CuO could be achieved by varying reaction temperature,surfactant and the anion type of 1,3-dialkylimidazolium based ionic liquids.The formation mechanism of CuO nanoplatelets was discussed.XRD,FESEM,and TEM/SAED were used...
