单分散的ca.在20/80的乙醇-水溶液中,在超声辐射下合成了30 nm的磁性纳米粒子。乙醇-水溶液和超声波辐射都是合成单分散磁性纳米粒子的重要条件。乙醇-水溶剂一方面改善了磁铁矿颗粒的单分散性,另一方面限制了机械搅拌下磁铁矿的形成。在超声辐射下,在乙醇-水溶液中成功合成了100%立方体磁铁矿颗粒。
Monodispersed ca. 30 nm magnetite nanoparticles were synthesized in a 20/80 ethanol-water solution under ultrasonic irradiation. Both the ethanol-water solution and ultrasonic irradiation were important for the synthesis of the monodispersed magnetite nanoparticles. The ethanol-water solvent improved the monodispersibility of the magnetite particles, on the other hand, limited the formation of magnetite under mechanical stirring. The 100% cubic magnetite particles were successfully synthesized in ethanol-water solution under ultrasonic irradiation.
