In this paper,a thiol-functionalized nanophotocatalyst MPTES/TiO_2 was first synthesized by one-pot method using P123 as a template.X-ray diffraction confirms the complete anatase crystalline of thiol-functionalized TiO_2,N_2 adsorption-desorption isotherm demonstrated that these materials possess high surface area and mesoporous structure.The results of XPS show that MPTES has been successfully polymerized in mesoporous structured TiO_2.The photodegradation of phenanthrene(PHE) was investigated under visible light irradiation(λ>420 nm) to evaluate the photocatalytic activity of these materials.Based the experiment results of GC-Mass analysis,a possible mechanism was proposed.
