Abstract
Morphology control is always an attractive field in material synthesis. In this work, titania fibers were synthesized by solvothermal reaction starting from potassium tetratitanate. The reaction temperature was altered from 300 to 400 degree centigrade, and various solvents such as water, methanol and ethanol were used. The phase transformation behaviors were conducted by X-ray powder diffraction analysis and Raman spectroscopy. Morphologies of the smaples were observed through TEM and SEM method. The results revealed that by altering the reaction temperature and solvent, fibrous titanium dioxide with different crystalline phases could be obtained. The photocatalytic activities of the prepared titania fibers were also evaluated.
