Enhancing Photocatalytic Activity of Nitrogen Doped TiO2 for Degradation of 4-Chlorophenol under Solar Light Irradiation
The nitrogen doped TiO2 as heterogeneous photocatalyst via sol-gel method were successfully synthesized. The physicochemical, morphological and textural characteristics of the obtained TiO2 samples were characterized by advanced analysis techniques. The photocatalytic activity of the samples were evaluated for degradation of 4-CP under solar irradiation. The as-synthesized photocatalysts were c...
متن کاملPhotocatalytic degradation of methyl orange using TiO2:Mg2+/zeolite composite under visible light irradiation
Photodegradation of methyl orange was investigated using synthesized TiO2:Mg2+/zeolite as the photocatalyst. The photocatalyst was characterized by X-ray, XRF, FT-IR, and SEM. The photocatalytic activities of TiO2:Mg2+/zeolite samples were evaluated in the degradation of methyl orange under visible light irradiation. The appropriate content of Mg in the composite was obtained as 4.711 wt% with ...
متن کاملDegradation of Diclofenac Sodium under Solar Light Irradiation by Photocatalytic Performance of ZnO and V2O5
Pharmaceutical pollutants are one of the most important issues of modern life and their negative effects on the environment and human health are undeniable. In the present work, the effectiveness of the photocatalytic process was studied by two semiconductors (ZnO and V2O5) in order to remove the Diclofenac Sodium completely under solar irradiation. The study examined the impact of parameters s...
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 کاملPhotocatalytic Removal of Acid Blue 113 Dye from Aqueous Solutions Using Zinc Oxide-Kaolin Nanocomposite under Visible Light Irradiation
Background and purpose: Textile industries produce huge amounts of colored wastewater. Synthetic dyes cause serious problems to human health and aquatic organisms due to their toxic and carcinogenic properties. In this study, Acid Blue 113 (AB113), which is stable and persistent against conventional treatment methods was selected as the target contaminant. Materials and methods: The synthesis ...
