Preparation and Photocatalytic Properties of TiO₂/CMK-3 Composites

Abstract:

In this paper, TiO₂/ ordered mesoporous carbon (CMK-3) composites were prepared by hydrolysis method after electron beam (EB) pretreatment. The XRD results showed pure TiO₂/CMK-3 composites can be obtained under mild reaction conditions (0.06 M TiF₄ solution, and at 60 °C), and the SEM/TEM images showed that the TiO₂ was successfully grown onto the surface of CMK-3. The photocatalytic properties of TiO₂/CMK-3 composites were also investigated by methyl orange (MO) degradation under the UV irradiation. Results demonstrated that the TiO₂/CMK-3 composites have a good photodegradation for the MO.
