Abstract
The development of engineered nanostructures with precise morphology has gained significant attention due to new properties of these materials. Herein, we report a novel recipe to synthesize Ce1−xCuxO nanostructures via a hexamethylene triperoxide diamine assisted solvothermal method. The influence of Cu ion concentration (0.01≤x≤0.10) on the structure and morphology of the CeO nanocrystals was examined. The X-ray photoelectron spectroscopy demonstrated that the copper atoms tend to be incorporated into the CeO crystal structure in the form of Cu2+. At the Cu ion concentration x=0.09, the Cu-doped CeO2 displayed a very high saturation magnetic moment of 1.58μB/Co and coercivity of 154 G. The synthetic method designed in this work enhanced the ferromagnetic properties of the Ce1−xCuxO nanostructures compared to the materials obtained by conventional techniques.
