Photocatalytic degradation of methylene blue (MB) in aqueous solution was investigated using TiO2 coated on various acid modified activated carbon fiber (ACF). The ACFs/TiO2 composites were prepared from titanium n-butoxide (TNB) as titanium precursor and various acid modified ACFs. The prepared samples are heat treated at 973 K. Then the ACF/TiO2 composites were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray analysis (EDX). Moreover, photocatalytic degradation of MB by the ACF/TiO2 composites was determined under UV irradiation. The results shows that the photocatalytic activity of ACF/TiO2 composites (AT1~AT4) prepared with TNB and various acid modified ACF was much better than that of ACF/TiO2 composite (AT) prepared with TNB and nonacid modified ACF, and the effects improved with order of sample AT3 > AT4 > AT1 > AT2.
