|
摘要
以聚丙烯腈基碳纤维(CF)为基体,TaCl_5和乙酸钠为原料,十六烷基三甲基溴化铵(CTAB)为表面活性剂,通过溶胶-凝胶法和浸渍提拉法将纳米NaTaO_3薄膜负载于CF上,制备得到高效光催化特性的复合材料。采用SEM、TEM、XRD等表征了NaTaO_3-CF的形貌和结构,以罗丹明B(RhB)溶液为目标降解物,测试了NaTaO_3-CF复合材料的光催化性能。结果表明:所制备的NaTaO_3-CF复合材料具备良好光催化活性和重复使用稳定性,暗中吸附30min、光照80min时,对RhB的去除率为99.35%,5次循环使用后,去除率为89.17%,其光催化反应过程符合伪一级反应动力学模型。
The NaTaO_3-carbon fiber(CF)composite with excellent photocatalytic activity was prepared through sol-gel method combined with dip-coating technique by using TaCl_5 and sodium acetate as the raw materials,cetyl trimethyl ammonium bromide(CTAB)as the surfactant.The morphology,crystalline phase and photocatalytic properties of NaTaO_3-CF composites were investigated by SEM,TEM and XRD.The dye rhodamine B(RhB)was used as a model contaminant to evaluate the photocatalytic activity of NaTaO_3-CF composites.The results indicate that NaTaO_3-CF composites have excellent photocatalytic performance and the removal ratio of RhB is achieved 99.35% under dark adsorption for 30 min and irradiation for 80 min.The NaTaO_3-CF composites also present favorable stability and photocatalytic activity after recycling,the removal ratio of RhB is remained above 89.17%after five cycles.The photodegradation of RhB is in accordance with the pseudo first order reduction kinetics model and could be described by this kinetic model.
