摘　　要：采用钛酸四正丁酯为原料 ,用溶胶 -凝胶法在粘胶基活性炭纤维 (ACF)毡表面制备了锐钛矿型的二氧化钛粒子 ,并用XRD ,SEM进行了表征。用聚乙烯醇、柠檬酸等不能加热再生的大分子吸附质考察了负载二氧化钛的ACF毡的光催化降解再生性能 ,并与没有负载二氧化钛的ACF毡的吸附性能作了比较。结果表明 ,负载二氧化钛粘胶基的ACF毡具有高效的光催化再生能力和良好的吸附能力。Anatase TiO 2 particles were prepared on viscose-based activated carbon fiber(ACF) felts surface via sol-gel method with tetra-n-butyl titanate as precursor and characterized by XRD and SEM. By using polyvinyl alcohol and citric acid as high-molecular adsorbates which can not be removed by traditional heat treatment methods, the photocatalytic regenerability of the felts ACF felts loaded with TiO 2 was investigated. And its adsorbability was compared with that of ACF felts without TiO 2. The results showed that the viscose-based ACF loaded with TiO 2 had higher photocatalytic regenerability and better adsorbabilities.
