Preparation and characterization of S-doped titanium dioxide wrapped by reduced graphene oxide for photocatalytic behaviors. |
| 초록 |
In this work, S-doped TiO2 were prepared by sol-gel and various weight ratio of reduced graphene oxide composites by hydrothermal method for photocatalytic activities. Structural properties of the composites were characterized by X-ray diffraction spectroscopy (XRD) and transmission electron microscopy (TEM). The surface areas and pore size distributions were calculated by Brunauer-Emmett-Teller (BET). Photocatalytic activities were measured using rhodamine B solution under simulated solar light irradiation. Photodecomposition rate of S-TiO2/reduced graphene oxide composites were improved compared to pure TiO2. The results indicated that reduced graphene oxide reduced band gap energy and decreased recombination ratio of excited electrons. |
