晶态介孔金属氧化物的合成研究进展

Progress in Synthesis of Crystalline Mesoporous Metal Oxides

晶态介孔金属氧化物与相应的无定形材料相比具有更加优异的催化、光学、电学、磁学和力学等性能,具有较宽的应用范围,是近年来介孔材料合成的热点。本文主要对晶态介孔金属氧化物的制备方法,包括非晶晶化法、蒸发诱导自组装法和硬模板法进行了介绍,并对这些方法的优缺点进行了比较。

The crystallized mesoporous metal oxides have the superior catalytic, optical, electrical, magnetical and mechanical performance and widely application range than their amorphism. The crystallization is one of the most important topics of synthesis of mesoporous materials. This paper began with a brief review of the preparation methods for mesoporous metal oxides with crystalline wall, including amorphous crystallization, evaporation-induced self- assembly （EISA） method and hard template synthesis method. Moreover, the advantages and disadvantages of these methods were compared.
