纳米氧化铝制备方法研究进展

Recent development in the preparation of nano-alumina

纳米氧化铝作为一种重要的纳米材料,在陶瓷材料、催化剂载体等领域有着广泛的应用。首先介绍了纳米氧化铝的主要形态,然后分别对纳米氧化铝的3种主要的制备方法(固相法、气相法、液相法)进行说明,并着重论述了目前应用比较广泛的液相法和介孔纳米氧化铝的制备。最后,提出了一些在纳米氧化铝的制备研究中有待解决的问题。

As an important nanomaterial, nano - alumina has wide applications in many fields, such as catalyst supports and ceramic materials. The main morphologies of nano - aluminas are first introduced, and then three main preparation methods of nano - alumina （ the solid method, the gas method, the liquid method ） are described respectively, especially the liquid method and preparations of mesoporous alumina, which are used widely at present, are emphatically stated. Finally, some problems in the preparation of nano - alumina to be solved are pointed out.
