| 摘要： | Nitrogen-modified anatase titanium dioxide catalyst was synthesized and coated on glass-fiber by dip-coating sol-gel method in the presence of urea. The catalyst was characterized with scanning electron microscopy, X-ray photoelectron spectroscopy, UV-Vis diffuse reflectance spectroscopy. The results indicated that TiO2 were modified by surface-polycondensation materials and nitrogen was in substitutional and interstitial states. Additional X-ray diffraction analysis indicated that anatase to rutile transition was restrained up to 800 degrees C. Its photocatalytic activity was further evaluated by photodegradation of ibuprofen under simulated solar irradiation, and the results indicated that nitrogen-modified TiO2 was influenced significantly by urea loading and calcination temperature that resulted in crystal size change and nitrogen states. The optimal doping dose and calcination temperature were 11 % We and 500 degrees C, respectively. Newly fabricated N-modified TiO2 photocatalysts coated on glass fiber were efficient for ibuprofen removal under simulated solar irradiation. |
