Influence of reduced graphene oxide on photocatalytic degradation efficiency of leaf-shaped titanium oxide via electrospinning |
| 초록 |
In this work, TiO2 fibers with added polyvinylpyrrolidone(PVP) were prepared by electrospinning 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 TiO2/reduced graphene oxide composites were improved compared to pure TiO2. The results indicated that reduced graphene oxide affect to band gap energy and decreased recombination ratio of excited electrons. |
