The of Pt-loaded g-C3N4/ZnO nanofibers were prepared via electrospinning and hydrothermal method. The as-prepared composite photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS), and UV-vis diffuse reflectance spectroscopy (UV-Vis DRS). Photocatalytic activities were measured using rhodamine B solution under simulated solar light irradiation. Photodecomposition rate of Pt-loaded g-C3N4/ZnO nanofibers were improved compared to pure ZnO. The results indicated that reduced Pt-loaded g-C3N4 band gap energy and decreased recombination ratio of excited electrons. |
