尺寸可控的单分散四氧化三铁微球的省时制备
A Time-Saving Method to Prepare Monodisperse Fe3O4 Microspheres with Controllable Sizes and Morphologies
摘要
Abstract
Monodisperse Fe3O4 microspheres with tunable diameters and high magnetic saturation were synthesized by a solvothermal reduction method.It was found that the morphology and structure of the Fe3O4 microspheres could be tuned by simply altering the amount of the reactants such as ferric chloride,sodium acetate,water,and the reaction time.The Fe3O4 microspheres obtained via this method possessed high purity,crystallinity,and a nearly spherical shape.Furthermore,they were monodispersed and no aggregation was found.Such monodisperse Fe3O4 microspheres had tunable diameters of 400-700 nm and the fabrication time was only 2-4 h.The products showed high magnetic saturation values,and their yields were typically more than 94％.关键词
