模板法制备纳米金属氧化物材料现状及发展趋势

Status and development of nanostructured metal oxide by templated synthesis

模板合成法是制备纳米材料的一种重要合成方法。模板又可分为物理模板、化学模板和生物模板,这些模板被用来制作各种形态的纳米氧化物材料,如粉体、薄膜、纳米丝(线、带、棒、管)和孔状等,但两种模板各有优劣。首先介绍了模板的结构和制备方式;其次分析了不同方法的发展现状,讨论了这些方法的优势与不足;最后根据当前面对的困难和未来面临的挑战,讨论了模板法制备纳米金属氧化物的发展趋势。

Templating consists of physical,chemical and biological template,they all have both advantages and disadvantages,used to make a variety of nano-oxide materials,such as powder,film,nanowire(wire,tape,rod,tube)and pore.Firstly,the structure and organization of the various templates,and preparing nanostructured metal oxides by template method in recent years were introduced.Then recent development in this area was analyzed,and discussed the superiority and weaknesses of these methods in detail.Finally followed by studied templated synthesis perspective on the state of the field and potential future directions according to the current difficulties and future challenges.
