Abstract

C60-TiO2-ZnO, C60-ZnO, C60-TiO2 nanocomposites were synthesized using sol-gel method. Structural, chemical, and optical properties of nanocomposites were characterized using X-ray diffraction (XRD), tunneling electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, and photoluminescence (PL) spectroscopy. In addition to the fullerene peak, structural results in C60-ZnO samples show the wurtzite hexagonal structure of zinc oxide. The peaks related to both anatase and rutile phases are observed in the sample of C60-TiO2 composite. All peaks related to fullerene (C), wurtzite phase of zinc oxide (W) and anatase (A) and rutile (R) phases of titanium dioxide are also exactly the same as C60-ZnO and C60-TiO2 single composites in XRD analysis results of C60-TiO2-ZnO nanocomposites. The results of TEM images show that fullerene nanoparticles are located outside the surface of the zinc oxide and titanium dioxide nanoparticles. Titanium nanoparticles is less than 30nm and zinc oxide nanoparticles is less than 50nm in size. The photoluminescence (PL) spectrum measured for C60-TiO2-ZnO nanocomposites is much weaker than C60-ZnO and C60-TiO2 composites. According to TEM results, photocatalytic results show that C60-TiO2-ZnO nanocomposite have the highest percentage of dye degradation and the best photocatalytic properties due to having the best scattering.
