Evaluation of Nb2O5 and Ag/Nb2O5 in the photocatalytic degradation of dyes from textile industries

The textile industries are distinguished by the use of dyes that are applied to textiles. Dyes are pollutant materials that are difficult to decompose by microbiological treatment. An alternative way to prevent contamination of the environment by dyes is the oxidation of these materials through photocatalysis, a process by which illumination of an oxide semiconductor produces photoexcited electrons and cations that migrate over the surface of the oxide, effectively participating in the chemical reaction. The purpose of this work is to synthesize catalysts and study their performance in the pho...
