- Abstract
ZnO and TiO2 nanoparticles (NPs) and ZnO/TiO2 nanocomposites (NCs) were prepared by a solution combustion synthesis method. The samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and ultraviolet- visible spectroscopy. The photocatalytic activity of the ZnO/TiO2 NC under sunlight for the degradation of methylene blue (MB) and crystal violet (CV) was compared with that of the individual ZnO and TiO2NPs. The effects of the sample concentration and contact time on the degradation efficiency of both dyes were investigated. The contact time was found to have greater impact on the degradation of the dyes than the sample concentration used for degradation. The ZnO/TiO2NC had 5% greater dye removal efficiency than the individual ZnO or TiO2NPs.
