Low-Dimensional ZnO Nanomaterials

本文综述了近年来ZnO纳米材料制备的一些新方法,简单比较了各种方法的优缺点;讨论了制备不同形貌的ZnO纳米材料的影响因素,其中重点探讨了表面活性剂的作用;介绍了ZnO纳米材料的性质及其可能的应用领域,并对ZnO纳米材料的发展前景进行了展望。

Some new preparation methods of ZnO nanomaterials in recent years, including ionic liquid method, RF magnetron sputtering route, electrochemical synthesis, pulsed laser ablation deposition technique, hydrothermal approach, are presented in this paper. The advantages and disadvantages of these methods are simply summarized. The factors of affecting the morphology of ZnO nanomaterials such as reaction temperature, time, pH, sorts and concentrations of reactants and surfactants are mentioned. Since the surfactant usually plays an important role in the controlled synthesis of ZnO nanocrystals with certain shape in solution phases, many surfactants such as SDS, CTAB, HMTA, PVP, PEG and PMMA are discussed. The potential applications of ZnO nanomaterials in the commodity, medicine, catalyst, information record and store, absorption wave material, rubber and dope industry are introduced and the future development in ZnO nanomaterial research field is supposed.
