摘　　要：采用两相种子介导法以锰油酸为前驱体制备了一种新型油溶性核壳结构Fe3O4@MnO纳米复合材料,直径约为15 nm。所制备的具有核壳结构的纳米复合材料是单分散且均匀的。该产物对2-羟基苯乙酮和1,2-二氨基苯的氧化环化反应表现出高且可循环的催化活性。与在环化反应中使用的其他报道的催化剂相比,所制备的Fe3O4@MnO纳米复合材料绿色、廉价且更适合于大规模工业应用。A new type oil-soluble core-shell structure Fe3O4@MnO nanocomposites with diameter about 15 nm was prepared through two-phase seed mediate method with Mn-oleate precursors.The as-prepared nanocomposites with core-shell structure were monodispersed and uniform.The products exhibited high and recyclable catalytic activity for the oxidative cyclization reaction of 2-hydroxyacetophenone and 1,2-diaminobenzene.Compared with other reported catalysts used in this kind of cyclization reaction,the as-prepared Fe3O4@MnO nanocomposites are green,cheap and more suitable for large scale industrial applications.
