An efficient photocatalyst, nanoporous anatase TiO2 crystalline particles coupled by homogeneously dispersed Keggin unit, H3PW12O40/TiO2, was prepared by a simple and rapid process by combined sol–gel method. In this work activity and performance of a composite of TiO2/tungstophosphoric acid distributed onto the MCM-41 and Metal-MCM-41 are studied. The photocatalysts are employed for degradation of aniline which is one of the most serious pollutants in the environment. The prepared materials have been characterized by FTIR, BET and XRD. Our studies showed that the prepared materials have very high ability to adsorb aniline. Experimental data demonstrate that the reaction rate of decomposition of aniline is highest in TiO2/tungstophosphoric acid composites.
