摘　　要：磁性纳米材料作为新兴的无机功能材料,因其具有与常规材料不同的特殊性质,如高比表面积、强磁响应性、良好的化学稳定性和生物相容性等,被广泛应用在生物合成、生物分离、生物传感器、免疫测定、有机催化、药物传输、数据存储和环境治理等方面。目前合成磁性纳米材料的方法主要有化学共沉降法、高温热分解法、溶胶-凝胶法及热液法等。由于热液法具有条件简易、成本低廉、反应活性高、产率可观和绿色环保等优势,近年来受到了广泛的关注,并已应用在工业生产中。本文根据磁性材料组成与构成方式的不同,综述了热液法合成磁性纳米材料的研究进展。Nanoscale mgnetic materials as a kind of novel functional inorganic materials have been widely employed for biosynthesis, bioseparation, biosensors, immunoassays, organocatalysis, drug delivery, data storage and environmental improvement, due to their special properties such as high specific surface area, strong magnetic responsivity, chemical durability,biocompatibility and so on. So far, various synthetic methods have been devised to fabricate magnetic nanomaterials, including chemical coprecipitation, organometallic pyrolysis, sol-gel techniques, hydrothermal ＆ solothermal synthesis, etc. In recent years, hydrothermal ＆ solvothermal synthesis method has received extensive attention and is widely used in industrial production because of its advantages of simple reaction conditions, low cost, high activity, good yields and green-friendly. This review introduced four kinds of nanoscale magnetic material synthetized by hydrothermal or solvothermal, which are ferrite, composite material, magnetic alloy material, and other magnetic material.
