Synergistic effect of adsorption and photocatalysis for the degradation of toluene by TiO loaded on ACF modified by Zn(CHCOO).

Activated carbon fiber (ACF) was modified by Zn(NO), ZnCl, and Zn(CHCOO)), respectively, and then, TiO was loaded on the modified ACFs. The adsorption and photocatalysis performance were explored through the removal of toluene, and TiO/ACF- modified by Zn(CHCOO)) with the best toluene degradation performance was selected. The characterization results of a scanning electron microscope (SEM), X-ray diffraction spectra (XRD), and Fourier transform infrared spectrometer (FTIR) indicated that the samples were rough, and TiO was mainly loaded on the surface containing large amount of oxygen-containing functional groups in anatase phase.
