Journal ArticleDOI

Photocatalytic degradation of model textile dyes in wastewater using ZnO as semiconductor catalyst

TL;DR: The potential of a common semiconductor, ZnO, has been explored as an effective catalyst for the photodegradation of two model dyes: Methylene Blue and Eosin Y and substantial reduction of COD was achieved.
Journal ArticleDOI

Photo-reduction of hexavalent chromium in aqueous solution in the presence of zinc oxide as semiconductor catalyst.

TL;DR: In this paper, the conversion of Cr(VI) to Cr(III) in an aqueous medium by photocatalytic reduction using UV radiation and ZnO semiconductor catalyst has been investigated using potassium dichromate as the model compound.
Journal ArticleDOI

Zinc oxide nano-particles--sonochemical synthesis, characterization and application for photo-remediation of heavy metal.

TL;DR: The synthesized nanoparticles were used for the photocatalytic reduction of hexavalent chromium in aqueous medium under solar radiation and it was observed that the initial reduction rates varied with the difference in morphology of ZnO crystallites.
Journal ArticleDOI

Photocatalytic degradation of methyl orange dye by pristine titanium dioxide, zinc oxide, and graphene oxide nanostructures and their composites under visible light irradiation

TL;DR: In this article, the degradation of an azo dye, methyl orange (MO), was tested in simulated wastewater with different oxide nanomaterials acting as photocatalysts under visible light.
Journal ArticleDOI

On the adsorption and diffusion of Methylene Blue in glass fibers

TL;DR: The adsorption and diffusion phenomena of Methylene Blue dye on glass fiber have been explored and the diffusivity was found to be varying exponentially with the dye concentration.
