摘要
实验采用浸渍法研制了负载纳米TiO2及Cu/Pd金属离子的改性活性炭纤维(ACF)功能材料。利用扫描电子显微镜(SEM)、X射线光电子能谱(XPS)和表面孔隙度分析仪对材料的微观结构进行了表征。在自制的实验台上进行低温等离子体协同改性ACF净化甲醛的实验研究。研究结果表明:改性ACF有利于甲醛净化,其中负载纳米TiO2改性方案最佳;低温等离子协同TiO2/ACF净化效果最好,其效率高达94%。
Activated carbon fiber （ACF） was transnatured with nano-TiO2 and Cu/Pd ion via dipping method. The mierostructure of the prepared materials was characterized by SEM, XPS and specific area/porosity analyzer. The experiments for formaldehyde removal by the non-thermal plasma combined with prepared materials were carried out on self-designed test-bed. The results indicated that the transnatured ACF avail formaldehyde reduction, especially for the ACF transnatured with nano-TiO2. The non-thermal plasma combined with TiO2/ACF can reduce formaldehyde significantly with the removal efficiency of 94%.
