Preparation and Photocatalytic Activity of Terbium Doped TiO2 Pillared Bentonites
Abstract:
The terbium doped TiO2 pillared bentonites (Tb-TiO2-PILCs) were prepared with Ti(i-C3H7O)4 and Tb2O3 as precursors by the sol-gel method.Characteristics of Tb-TiO2-PILCs were examined with XRD and BET.Tb-TiO2-PILCs were used as composite photocatalysts for the photocatalytic degradation of sodium pentachlorophenate (PCP-Na).The results indicate that all the pillared bentonites contain TiO2 in the anatase phase.The photocatalytic activities of Tb-TiO2-PILCs are superior to that of non doped TiO2-PILC.Tb-TiO2-PILC shows the most photocatalytic activity when the mass percent of Tb/Ti is 0.5% among all the catalysts.In addition,the experiments also illustrate that the composite photocatalysts can be easily recovered,regenerated and reused.
