Halloysite (HNTs)-TiO 2 -Ag composites were fabricated by depositing anatase TiO 2 and nano Ag particles on the HNTs surfaces. The composite was characterized with corresponding instrumental analysis methods. Compared with HNTs-TiO 2 composites, the HNTs-TiO 2 -Ag composites exhibited better photocatalytic activity in the decomposition of MB and the persistent organic pollutant 4-nitrophenol(4-NP) under UV irradiation. After 2.5 hours of UV light irradiation, HNTs-TiO 2 -Ag composites removed about 97.63% and 51% of MB and 4-NP, respectively.
