We prepared CNT/TiO2 composites by using pre-oxidized multi-walled carbon nanotubes with different titanium alkoxide precurosrs in benmzene solvent. The composites were comprehensively characterized by Brauer-Emett-Teller surface area, transmission electron microscopy, X-ray diffraction and energy dispersive X-ray analysis. Furthermore, we used the prepared CNT/TiO2 composites to decompose the piggery waste under UV irradiation. The decomposition effect was analyzed by using the chemical oxygen demand method, FT-IR spectra, absorbance and total organic carbon. According to the results, after UV irradiation for 300 min, the chemical oxygen demand value was decreased 50% and the organic compounds in piggery was were degraded to other matters.
