Photocatalytic Degradation of Organic Dye under UV-A Irradiation Using TiO2-Vetiver Multifunctional Nano Particles
The properties and photocatalytic performance of anatase nanoparticles of pure TiO₂ and a core-shell structure of TiO₂ on calcined vetiver grass leaves have been compared. Samples were fabricated by sol-gel and heating at 450 °C for 5h.The comparison was based on data for X-ray diffraction(XRD), UV-Vis spectrophotometry, photoluminescence, transmission electron microscopy, specific surface area...
متن کاملPhotocatalytic degradation of some organic dyes under solar light irradiation using TiO2 and ZnO nanoparticles
Nanoparticles of the ZnO and TiO2 were synthesized and the physicochemical properties of the compounds were characterized by IR, X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The XRD patterns of the ZnO and TiO2 nanoparticles could be indexed to hexagonal and rutile phase, respectively. Aggregated nanoparticles of Z...
متن کاملتجزیه فتوکاتالیستی متیلن بلو با استفاده از نانوذرات اکسید روی
Backgrounds and Objectives: Textile industrial wastewaters are one of the important sources of environmental contaminants. In the recent years, use of advanced oxidation processes, by producing highly active and reactive components such as hydroxyl radicals has been proposed. The aim of this research is photocatalytic degradation of methylene blue dye using the ZnO-nanoparticle with UVA irradia...
متن کاملPhotocatalytic Degradation and Mineralization of Reactive Textile Azo Dye Using Semiconductor Metal Oxide Nano Particles
The textile industry consumes considerable amounts of water during the dying and finishing operations. Dyes extensively used are found to be toxic and considered to be resistant to biodegradation. In this work a detailed investigation of heterogeneous photocatalytic degradation of Navy blue HE2R 1 (NB), azo dye of reactive class is presented using UV/P25TiO2/ZnO2/H2O2 process in aqueous suspens...
