α-Fe2O3空心球的溶剂热合成与表征

摘要

Uniform α-Fe2O3 hollow microspheres with a diameter of about 900 nm were synthesized by a polyethylene glycol ( PEG-400) -assisted solvothermal method with FeCl3 · 6H2O as the raw material and ethanol as the solvent. The products were characterized by powder X-ray diffraction ( XRD) , scanning electron microscope ( SEM) ,and transmission electron microscope ( TEM).%以FeCl3·6H2O为原料,乙醇为溶剂,采用聚乙二醇(PEG-400)辅助的溶剂热法制备了大小均匀的α-Fe2O3空心徽球,其直径约为900 nm,粒径分布均匀.产物经X射线衍射仪(XRD)、扫描电镜(SEM)和透射电镜(TEM)进行了表征.
