Controllable electrochemical synthesis of CoFe2O4 nanostructures on FTO substrate and their magnetic properties

CoFe2O4 nanosheets (NSs) and nanoparticles (NPs) were successfully synthesized on F-doped SnO2 coated glass (FTO) substrate via a facile and controllable electrodeposition method. X-Ray photoelectron spectroscopy (XPS) results indicated that the CoFe2O4 NSs and NPs have different distributions of Co and Fe cations over tetrahedral and octahedral sites. The magnetic measurements showed that the prepared CoFe2O4 NSs exhibit higher value of magnetic properties, which can be mainly ascribed to the variation of the cation distribution.
