Abstract

Abstract Nanostructured TiO 2 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 TiO 2 samples were prepared using various temperatures and were studied for the photocatalytic degradation of methylene blue. The photocatalytic efficiency of TiO 2 was observed to increase by activating the TiO 2 surface using nanoporous PS. The photocatalytic performance of the synthesized samples showed a higher performance using molecular O 2 , which was purged through the reactor.
