Structure and Magnetic Properties of Co-doped TiO2 Nanotubes by Aqueous Solution Method

摘要：

The Co-doped titanium dioxide nanotubes were synthesized via the aqueous solution reaction. After hydrogenation,room temperature ferromagnetism (RTFM) was found in the cobalt doped titanium dioxide nanotubes at 300k by the vibrate sample magnetometer. As the concentration of cobalt increased,the observed ferromagnetism became stronger. The X-ray diffraction,scanning electron microscopy,high-resolution transmission electron microscopy and energy dispersive X-ray spectroscopy were performed and excluded the existence of cobalt cluster. Therefore,the magnetic ions and oxygen vacancies induced by hydrogenation contribute to the observed ferromagnetism at 300K.
