Synthesis of amine functionalized ZnO and its photocatalytic activity in micellar solution under UV irradiation |
| 초록 |
Zinc oxide (ZnO) nanoparticles were synthesized by simple sol-gel method and characterized by high-resolution transmission electron microscopy (HR-TEM), x-ray diffraction (XRD) and UV-Vis spectroscopy. To investigate photocatalytic performance in micellar solution, the surface modification of ZnO was inevitable. The surface of ZnO nanoparticle was modified by 3-Aminopropyltriethoxysilance (APTES) and measured by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FT-IR). The photocatalytic activity of the surface modified ZnO was evaluated by photocatalytic degradation of methylene blue in aqueous solution in the presence of different kinds of surfactant. The effect of charges of surfactant head goup on photocatalytic efficiency was investigated. The results show that the photocatalytic activity of modified ZnO particles in the presence of micelle is enhanced remarkably. |
