【摘要】 以乙酰丙酮铁为原料、一缩二乙二醇为溶剂,通过高温液相还原法制备磁性纳米颗粒。经X射线粉末衍射、傅里叶变换红外光谱、热重-差热分析仪、原子发射光谱等方法对磁性纳米颗粒进行了表征,测定其粒径、晶体类型并计算其浓度。本实验涉及纳米材料合成和表征相关知识,适合用作高年级本科生的综合化学实验,有助于培养学生的科研思维,激发学生的研究兴趣。更多还原

【Abstract】 Magnetic nanomaterials are synthesized by reducing iron(III)acetylacetonate,Fe(acac)3 in diethylene glycol(DEG)solvent.As-prepared magnetic nanomaterials are characterized by X-ray powder diffraction,FTIR spectroscopy,thermal analysis and ICP-AES to obtain their size and crystal information as well as determinate their molar concentrations.The details of nanomaterials’ synthesis and characterization are involved in this experiment,which is suitable for senior undergraduates as a comprehensive chemical experiment.This experiment is helpful to initiate students’ interests in science and enhance their research capabilities.更多还原
