Abstract

Thiourea-modified ZnO nanoparticles were prepared by the microwave-assisted method. The nanoparticles were characterized by X-ray diffraction (XRD), High-resolution transmission electron microscope (TEM), UV-Vis absorption spectroscopy (UV-Vis) and X-ray photoelectron spectroscopy (XPS). ZnO nanoparticles presented typical wurtzite structure. Microwave-assisted method and thiourea modifying reduced the particle size of ZnO corporately and the particle size of 2.0 mol% thiourea/ZnO was about 3 nm. The photocatalytic efficiency of thiourea-modified ZnO was influenced by the molar precent between thiourea and ZnO and 2.0 mol% thiourea/ZnO had the highest photocatalytic activity. The degradation rate of 30 mg/L C.I. Reactive Blue 4 could get to 85% in 50 min at room temperature when the concentration of 2.0 mol% thiourea/ZnO was 0.10 g/L.
