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.

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.

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.

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.

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.
