| Abstract: |
| Titanium dioxide sheet photocatalysts composed of interwoven microstrips were successfully synthesized using filter paper as templates. The synthesized samples were characterized by means of Fourier transform infrared spectroscopy, surface area analyzer, thermogravimetric analysis, powder X-ray diffraction, and scanning electron microscopy. The photocatalytic activities of the samples were evaluated by the degradation of methyl orange in an aqueous solution under UV-illumination. The results demonstrated that the paper-like TiO2 sheets with the optimum proportion of anatase/rutile (10/1) had the highest photoactivity. And the presence of the filter paper fiber can improve the crystallinity, raise the anatase-rutile transformation temperature and contribute to the formation of being paper-like. A detailed formation mechanism for TiO2 sheets is proposed. |

| 摘要: |
| 以滤纸为模板成功制备了由微带组成的二氧化钛纸光催化材料，利用红外光谱、热重量分析、X射线衍射、扫描电子显微镜对其进行了表征. 通过对甲基橙溶液在紫外光下的降解，考察了制得样品的光催化性能. 结果表明：锐钛矿/金红石比为10:1的二氧化钛纸具有最高的催化活性，且滤纸纤维提高样品的结晶度和锐钛矿的相转化温度. 并讨论了对二氧化钛纸的形成机理. |
