摘　　要：在十六烷基三甲基溴化铵(CTAB)/正戊醇/异辛烷/水构成的油包水型(W/O)微乳体系中合成了膜状及50nm立方状的Co-Fe普鲁士蓝类配合物(cobalt-iron Prussian blue analogues).研究了w值(水与CTAB的物质的量的比)、反应物浓度和反应温度对产品形貌的影响.并用原子力显微镜(AFM),透射电子显微镜(TEM),电子能谱(EDS),X射线光电子能谱(XPS)和红外(IR)对产品进行了表征.Films and cubic nanoparticles with diameters of about 50 nm of cobalt-iron Prussian blue analogues （Co-Fe PBA） were synthesized in cetyl trimethyl ammonium bromide （CTAB）/n-pentanol/isooctane/ water reverse microemulsion. The effects of the water-to-surfactant molar ratio （w）, the concentration of reactants and the reaction temperature on the morphology of products were studied. The products were characterized by atomic force microscopy, transmission electron microscopy, energy dispersive spectroscopy, X-ray photoelectron spectroscopy and infrared spectroscopy.
