摘　　要：晶态介孔金属氧化物材料因具有窄的孔径分布、大的比表面积、有序的孔道结构以及高度晶化的孔壁而在工业催化、光电等领域有着广泛的应用。在各种制备方法中,硬模板法因制备方法简单、条件温和、产物孔道结晶度高而受到了广泛关注。对硬模板法中介孔硅模板和介孔碳模板进行了介绍;总结了近年来硬模板法合成氧化铬、氧化铁、氧化铈、氧化镁和氧化钴等晶态介孔材料的研究进展;概述了该材料的发展趋势和应用前景。The crystallized mesoporous metal oxides are widely used in the realm of industrial catalysis and optoelectronics research, for their remarkable characteristics which include narrow pore size distribution, high specific surface area, ordered pore structure and highly crystallized pore walls. Hard-template method has drawn great public attention because of its simple preparation method and mild conditions. In addition, the products prepared by this method have greatly crystallized pore walls. The mesoporous silica templates and mesoposous carbon templates of hard-template method are briefly introduced in this paper. The progress on synthesis of crystalline mesoporous metal oxides including Cr2O3, Fe2O3, CeO2, MgO, and Co3O4, is summarized. The development trend and application prospects are put forward as well.
