제목 A study on photocatalytic behaviors of mesoporous anatase TiO2 sphere/multiwalled carbon nanotubes nanocomposite
초록  In this study, mesoporous anatase TiO2 spheres decorated with multiwalled carbon nanotubes were prepared by sol-gel method and solvothermal process. The morphologies of the composites were confirmed by scanning electron microscopy (SEM). The crystallization of samples was investigated by X-ray diffraction (XRD). The textural properties of samples were examined by N2 adsorption-desorption isotherm at 77 K. The photodegradation efficiency was tested using rhodamine B under solar light irradiation. As a result, nanocomposites showed better photocatalytic performance than bare TiO2, since MWCNTs plays an important role as good electron traps and carriers for the retardation of electron-hole recombination. In addition, creation of mesopore structure of TiO2 improved adsorption properties, leading to increased interaction toward rhodamine B onto the surface of mesoporous TiO2 spheres/MWCNTs nanocomposites.
