中文摘要 | The nitrogen-doped TiO/sub 2/-ZrO/sub 2/ co-extruded film with the grain size of 40-50 nm has been synthesized by sol-gel process in electric field. The XPS and XRD analysis show that some of the nitrogen-atom substitutes the oxygen-deficient in the co-extruded film and TiO/sub 2-x/N/sub x/ compound appears. The Einstein shift in the optical absorbance spectrum of the nitrogen-doped co-extruded film is also observed by UV-VIS, and the cut wavelength approximates 550 nm. The photocatalysis result shows that the inactivation rate to colibacillus increases largely for the nitrogen-doped co-extruded film at both of UV and VIS lights. It could be concluded that the doped nitrogen substitution in form is effective to narrow the gap and enhance the photocatalysis. |
