Preparation and Characterization of Dysprosium-Doped Titanium Dioxide Photocatalyst by Sol-Gel Method

Abstract

In this work, the dysprosium-doped titanium dioxide nanostructures were prepared by sol-gel method and characterized as photocatalysts for environmental applications. The morphology, composition, particle size, surface area and energy band gap of the prepared samples were studied. The effect of dysprosium ions on the photocatalytic properties of the prepared titanium dioxide nanostructures was studied and analyzed by the photocatalytic decomposition of potassium permanganate in aqueous slurry.
