Abstract :
Nanostructured TiO2 was synthesized by the sol–gel method. The titania was supported on nanoporous poly
(styrene-co-divinylbenzene) (PS). The samples were characterized by several techniques (scanning electron
microscopy, energy-dispersive spectroscopy, X-ray diffraction, and ultraviolet–visible spectroscopy). Three types of
TiO2 samples were prepared using various temperatures and were studied for the photocatalytic degradation of
methylene blue. The photocatalytic efficiency of TiO2 was observed to increase by activating the TiO2 surface using
nanoporous PS. The photocatalytic performance of the synthesized samples showed a higher performance using
molecular O2, which was purged through the reactor.
