TiO2-organosilicone based hybrid catalysts functioned by Keggin-type heteropolyacid, TiO2-Si (Et)Si-H3PW12O40, were prepared via one-pot co-condensation method in the presence of a triblock copolymer surfactant (F127). The materials were well characterized by FT-IR, UV-vis DRS spectroscopy methods, and X-ray diffraction analysis to confirm the hybrid structure, to investigate correlation among TiO2-organosilicone matrix and H3PW12O40. Phtocatalytic tests show that, with a little amount of organosilicone and hybridization, the composite exhibits higher photocatalytic activity when decomposing the Rhodamine B ( RhB ) than anatase TiO2.
