【摘要】 制备了活性炭纤维负载二氧化钛复合催化剂ACF/TiO2,并在紫外光下降解甲基橙以考察其催化活性。并在同等条件下,对未负载二氧化钛的活性炭纤维空白样品进行了对比实验;同时还考察了ACF/TiO2的循环使用寿命。结果表明,ACF/TiO2降解能力大于未负载的活性炭纤维,其降解能力是吸附性能和光催化性能的协同作用,并拥有较长的循环使用寿命。更多还原

【Abstract】 Activated carbon fiber loading titanium dioxide(ACF/TiO2) composites have been prepared by sol-gel method.The photocatalysis characteristic of ACF/TiO2 was researched in the experiment of disintegrating of methyl orange under UV light.The results indicate that the photocatalytic degradation efficiency of ACF/TiO2 is better than that of un-loaded ACF,and the reason is ascribed to the synergy of absorption and photocatalytic performance.Moreover,ACF/TiO2 can be repeatedly used for several times.更多还原
