Preparation & Characterization of Four Kinds of TiO2/CNTs

With Ti(C4H9O)(4) as raw material, and with untreated CNT, carboxylated CNT, hydroxylated CNT and carbon fiber as carriers respectively, four kinds of TiO2-CNT composites were successful prepared orderly under the calcinated conditions of 400 to 800 degrees C by sol-gel method. The morphology and structure features of these composites were characterized by scanning calorimeter (DSC), X-ray diffraction (XRD) and scanning electron microscope (SEM) respectively. The results indicate that, as coexisting carrier material, the carbon nanotube had obvious effects on the morphology and structure of TiO2 nanocrystal. However, when being carboxylated or hydroxylated, though multi-walled carbon nanotube has still obvious effects on crystalline form of TiO2, threre are no remarkable impacts on its morphology.
