| Abstract |
Recently, with the growing demand for clean and comfortable environment, purification technologies with high efficiency and low cost are urgently in need. Thus for the remediation of hazardous wastes, many efforts have been taken in recent years by the use of ZnO catalyst for the photodegradation of toxic dye pollutants. ZnO having band gaps of 3.37eV at room temperature offers several advantages over other catalytic materials such as higher quantum efficiency, environmentally friendly, low cost and superior in photocatalytic activity. In this study, a facile and efficient approach for the fabrication of ZnO nanoparticles has been demonstrated. Microstructure and physical properties of the ZnO nanoparticles were investigated by field emission scanning microscopy (FE-SEM), transmission electron microscopy (TEM), infrared spectroscopy (IR) and steady state spectroscopic method. In addition, studies of the photocatalytic properties of the ZnO nanoparticles by exposure to UV irradiation of organic pollutants have demonstrated that they have potential photocatalytic applications. |
