| 摘 要： | 将溶胶-凝胶法与水热法相结合制备活性碳纤维(ACF)-Ag-TiO2纳米纤维复合材料,利用扫描电镜、透射电镜、能量色散型X射线光谱仪对ACF-Ag-TiO2纳米纤维复合物的表面形貌及晶型进行表征,并以甲基橙的脱色降解为模式反应,考察样品的光催化性能。结果表明,ACF-Ag-TiO2纳米纤维长度为48μm,直径约为58μm,直径约为550 nm;制备的材料中Ag元素的质量分数为0.5%时,ACF-Ag-TiO2的催化效果最优,光照30 min后对甲基橙的降解率为95%。

| Abstract: | Activated carbon fiber(ACF)-Ag-TiO2 nanofiber composite materials were prepared using hydrothermal method combining with sol-gel method.The samples were analyzed by SEM,TEM and EDS.Taking methylene orange degradation as a model reaction,the photocatalytic property of the material was investigated.The results indicate that the length of nanofibers is between 4 and 8 μm,and the diameter is between 5 and 50 nm.As the mass fraction of element Ag doping in the prepared materials is 0.5%,the photocatalysis efficiency was at the maximum.The photocatalysis efficiency on the methylene orange is up to 95% after lighting for 30 min. |
