| Abstract: | Ti1-xCoxO2 nanoparticles were synthesized by annealing dry gel in the air.The Ti1-xCoxO2 dry gel was produced by the reaction mainly between Tetra-n-butyl Titanate and cobaltous nitrate.The crystal structure and the magnetic properties of the Ti1-xCoxO2 nanoparticles were investigated by thermogravimetry-differential thermal analysis(TG-DTA),X-ray diffraction(XRD) patterns,Raman spectroscopy and vibrating sample magnetometer(VSM).It was found that the Co doped TiO2 nanopartilce is anatase structure when the... |
