对活性炭纤维性质和形貌进行了表征,探讨了活性炭纤维对TiO2光催化纸的光催化协同作用,并通过扫描电镜(SEM)观察了光催化纸的形貌结构以及TiO2的附着.结果表明,活性炭纤维的材质柔软、表面有深的沟槽、含氧基团数量较多;活性炭纤维配抄的TiO2光催化纸重复使用效率明显高于活性炭纤维吸附纸,吸附/光催化协同作用明显;连续使用两次时,其反应210min时甲醛的降解率均能达到90%以上;活性炭纤维光催化纸孔隙大,部分TiO2分布于活性炭纤维的沟槽内,有效增加了TiO2和活性炭纤维的接触面积.
The properties and morphology of activated carbon fiber were characterized, and the photocatalytic synergistic effect of activated carbon fiber on TiO2 photocatalytic paper was discussed. The morphology of photocatalytic paper and the attachment of TiO2 were observed by scanning electron microscope (SEM) Activated carbon fiber material is soft, the surface has deep grooves, a large number of oxygen-containing groups; activated carbon fiber photocatalyst copy with photocatalytic paper reuse efficiency was significantly higher than that of activated carbon fiber adsorption paper, adsorption / photocatalytic synergistic effect; continuous When using twice, the degradation rate of formaldehyde can reach more than 90% at 210min. The pores of activated carbon fiber photocatalytic paper are large and part of TiO2 is distributed in the groove of activated carbon fiber, effectively increasing the contact area between TiO2 and activated carbon fiber.
