Hydrothermal synthesis and magnetic property of Cu3(OH)2V2O7•nH2O

Copper vanadium oxide hydroxide hydrate (Cu-3(OH)2V(2)O(7)center dot nH(2)O) nanoparticles with mean size of about 100 nm were successfully synthesized by a simple hydrothermal method. The structure and morphology of the as-synthesized products were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), Raman spectra, and Fourier transform infrared spectra (FTIR). The composition and purity of the as-synthesized Cu-3(OH)2V(2)O(7)center dot nH(2)O nanoparticles were characterized by Energy disperse spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). The magnetic property of the as synthesized Cu-3(OH)2V(2)O(7)center dot nH(2)O nanoparticles was characterized by vibrant sample magnetometer. Magnetic hysteresis curve indicate that the as-synthesized nanoparticles are of weak ferromagnetic property at room temperature. (C) 2009 Elsevier B.V. All rights reserved.
