Polyionic Liquids (PIL) Promoted Ce Doped ZnO for the Photocatalytic Degradation of Rhodamine B (RhB)

A Comparative Photocatalytic Activity of ZnO/SiO2 and V2O5-ZnO/SiO2 by Investigating the Degradation of Rhodamine B

ZnO/SiO2 was prepared using sol-gel method, and vanadium particles were loaded on this nano-photocatalyst by wet incipient method. They characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) analysis andFouriertransform infrared spectroscopy (FT-IR). The XRD patterns showed that the zinc oxide samples have a wurtzite structure and vanadium dope...

Photocatalytic Activity of ZnO Nanoparticles (Bare, Doped and Co-doped with Mg and La) in the Removal of Rhodamine B from Aqueous Solutions by UVC Irradiation

Background & objectives: The organic dyes are environmental pollutants that pour into water sources by industrial wastewater. It is necessary to develop effective methods for removing pollutants. The aim of this study was to evaluate photocatalytic efficiency of bare ZnO nanoparticles doped with Mg and La (1 to 6% by weight) and Mg 5% -La 5% / ZnO and Mg6%-La4% / ZnO nanoparticles in the remova...

Photocatalytic degradation of methyl orange using ZnO and Fe doped ZnO: A comparative study

ZnO and 2% Fe doped ZnO photocatalytic nanomaterials were successfully synthesized by successive ionic layer adsorption and the reaction (SILAR) method. The characterizations of these nanomaterials were carried out using XRD, SEM and EDX techniques. XRD study shows that the samples have a hexagonal wurtzite crystal structure, size of which is in the range 21-23 nm. SEM shows nanoflakes or nano ...

Preparation and characterizations of CuO doped ZnO nano-structure for the photocatalytic degradation of 4-chlorophenol under visible light

In the present investigation, a ZnO nanostructure was synthesized by means of precipitation and sonochemical methods. The X-ray diffraction (XRD) pattern indicated that the wurtzite structure of ZnO had a hexagonal symmetry and there was no impurity. The average ZnO particles crystallite size was calculated at about 41 nm. The SEM and TEM images revealed nanostructure ZnO particles with a cauli...
