摘　　要：以聚乙烯基吡咯烷酮(PVP)为结构导向剂,并分别以乙二胺四乙酸二钠(EDTA)和柠檬酸(CA)为配体,合成了不同种形貌的SrCO3.用XRD,TEM和IR对产物进行了表征.结果表明,pH及PVP的质量和配体的类型等因素均对产物形貌有明显影响.PVP as a structure guide reagent, EDTA and CA as chelating ligand and capping reagent, different morphologies of SrCO3 nanostructures have been prepared successfully. The products were characterized by X ray diffraction （XRD）,transmission electron microscope （TEM） and infrared spectra （IR）. The experiment parameters, such as pH,the quality of PVP,the types of the chelating ligand were found to play significant role in determining the morphology.
