A new approach for the synthesis of Prussian blue nanoparticles using the cationic surfactant Cetyl Pyridinium Chloride (CPC) as capping agent has been developed in the present work. Powder X-ray diffraction, transmission electron microscopy, UV–vis absorption spectra, and IR spectroscopy were employed to characterize the product. The TEM image showed that the Prussian blue nanoparticles with d...
