文献名： Room temperature synthesis of rutile nanorods and their applications on cloth 作者： Bin Fei1,5, Zhaoxiang Deng2, John H Xin1,5, Yihe Zhang1,3 and Geoffrey Pang4 1 Institute of Textiles and Clothing, The Hong Kong Polytechnic University, Hong Kong 2 Department of Chemistry, University of Science and Technology of China, Hefei, People's Republic of China 3 Department of Materials Science and Technology, China University of Geosciences, Beijing, People's Republic of China 4 Department of Applied Physics, The Hong Kong Polytechnic University, Hong Kong 5 Authors to whom any correspondence should be addressed 摘要： In order to achieve better photocatalytic performance, rutile nanorods dispersed in anatase and brookite phases were synthesized from titanium isopropoxide (TIP) in a concentrated HNO3 solution at room temperature (23?°C). X-ray diffraction results indicated that the percentage of rutile increased with increasing peptization time. Scanning electron microscopy and and high-resolution transmission electron microscopy measurements revealed that the nanosized titania particles mainly consisted of granular anatase and brookite, and rod-like rutile. It was interesting that the stability of the colloid increased with increasing nanoparticle concentration, and the tricrystalline titania showed a photocatalytic activity higher than that of pure anatase. These nanocrystals were applied onto cotton fabrics, and achieved a promising bactericidal photocatalytic activity and excellent protection against UV radiation.
