Highly oriented cubic, hollow cubic and spherical nanoparticles of cobalt-iron Prussian blue analogues were synthesized in poly oxyethylene tertoctylphenyl ether (TritonX-100)/n-hexanol/cyclohexane microemulsion. The effects of the water-to-surfactant molar ratio (w), the reactant concentration and the reaction temperature on the morphology of cobalt-iron Prussian blue analogues were studied. The samples were characterized by transmission electron microscopy (TEM), field emission scan electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and infrared spectroscopy (IR).
