【摘要】 文章采用不同方法对活性炭纤维（ACF）进行改性，并将TiO₂负载在改性ACF上制成复合材料，通过对比不同方法制备的改性复合材料对甲苯的降解性能，选出性能最佳的TiO₂/Zn（NO₃）₂-ACF复合材料并进行表征。通过改变不同实验条件发现：在24 W紫外灯照射下，浸渍2次的TiO₂/Zn（NO₃）₂-ACF复合材料对1 000 mg/m³的甲苯气体去除率达到65%;经过3次循环再生后，复合材料的降解性能无明显下降，说明TiO₂/Zn（NO₃）₂-ACF复合材料具有良好的循环稳定性。更多还原

【Abstract】 In this study, activated carbon fiber（ACF） was modified by different methods, and TiO₂ was loaded on modified ACFs to prepare composite materials. The TiO₂/Zn（NO₃）₂-ACF composites with the best performance were selected and characterized by comparing the degradation performance of toluene by different modified ACF loaded TiO₂ composites. By changing different experimental conditions, it was found that under the irradiation of 24 W UV lamp, the toluene gas removal efficiency of TiO₂/Zn（NO₃）₂-ACF composite prepared by impregnation twice could reach 65% for 1 000 mg/m³. In addition, after three cycles of regeneration, the performance of the material did not decrease significantly, indicating that TiO₂/Zn（NO₃）₂-ACF composite had decent cycle stability.更多还原
