采用胶体晶体模板法制备了多晶尖晶石和钙钛矿型复合金属氧化物(ZnFe2O4、NiFe2O4和LaFeO3)三维有序大孔材料。90%以上的材料具有3DOM结构。尖晶石型或钙钛矿型混合氧化铁的晶体由柱状、四面体和正方形三个顶点组成。支柱连接四面体和正方形棱柱顶点，产生具有三维骨架结构的反蛋白石。
Three-dimensionally ordered macroporous (3DOM) materials of polycrystalline spinel- and perovskite-type mixed metal oxide (ZnFe 2 O 4 , NiFe 2 O 4 , and LaFeO 3 ) could be successfully fabricated using colloidal crystal template method in excellent yield. More than 90% of the obtained materials had the 3DOM structure. The crystallites of the spinel- or perovskite-type mixed iron oxide construct struts, tetrahedral and square prism vertexes. The struts connect the tetrahedral and square prism vertexes to produce inverse opals with skeleton structure in three dimensions.
