%X TiO2 pillared bentonite (TiO2-PILC) was prepared with an intercalation of polynu-clear titanium complex formed by reaction of Ti(i-C3H7O)4 and acetic acid. TiO2 pillared bentonites modified with platinum (Pt-TiO2-PILCs) were carried out via the photodeposition method. Characteristics of the pillared bentonites were examined by XRD, BET, TEM. TiO2-PILC and Pt-TiC-2-PILCs were used as composite photocatalysts in photocatalytic degradation of sodium pentachlorophenate(PCP-Na). The results indicate that all the pillared bentonites contain TiO2 in the anatase phase and with a mean crystallite size of TiO2 about 5nm. The photocatalytic activities of Pt-TiO2-PILCs are superior to that of TiO2-PILC. In addition, the experiments also illustrate that the composite photocatalysts can be easily recovered, regenerated and reused.
