摘要:

 由于納米材料具有不同于宏觀塊材的特性，諸如量子尺寸效應、小尺寸效應等，越來越多的科學家致力于納米材料的合成和介觀特性的研究，推廣其在現實生產生活中的應用。磁性納米材料，如鐵、鈷、鎳等，具有獨特的磁學和催化等介觀特性，近年來得到了廣泛關注。發展高度可控且溫和、簡便的合成方法，構筑具有優異特性的新型納米結構，實現對目標材料物理、化學性質的剪裁，已經發展成為無機納米材料合成的重要發展方向。目前，磁性納米材料的合成方法取得了廣泛的研究，可以有效實現磁性納米材料的可控合成及組裝。通過對材料的微結構調控可以有效控制材料的尺寸、形貌、成分及表界面性質，從而實現對磁性納米材料的磁學、催化等介觀性質的優化。

Abstract:

 Nanomaterials with small size and high specific surface area have many unique properties because of the small size effect and quantum size effect. As a result, nanomaterials have been widely investigated to develop their novel applications in daily life. Magnetic nanomaterials, for example， iron, nickel and cobalt, have attracted much more attention because of their outstanding magnetic, catalytic and electrochemical properties, which may bring extensive use in high density magnetic recording, sensors, catalysts and electrode materials.At present, the synthesis of inorganic nanomaterials mainly focuses on developing flexible, mild and simple methods, fabricating novel nanostructures with excellent qualities and tailoring the physical and chemical properties of objects. Motivated by the applied belief, a lot of methods have been developed for the synthesis of magnetic nanomaterials. These methods can effectively achieve the controllable preparation for the magnetic nanomaterials with typical structures, thus optimizing the magnetic and catalytic properties due to effectively controlled size, morphology and composition and the interface of the materials.
