Photocatalytic Degradation of Azure A Using N-Doped Zinc Oxide

摘要

Photocatalysis has been predicted as a promising technology for waste water treatment. N-dopedzinc oxide has been used as an effective catalyst for carrying out number of chemical reactions, butlimited work has been reported on use of N-doped ZnO as photocatalyst. In the present work, thephotocatalytic degradation of Azure A was carried out in the presence of N-doped zinc oxide andthe progress of the reaction was observed spectrophotometrically. The morphologies and structuresof the as-synthesized nanomaterials were investigated by using FT-IR and DRS techniques.On the basis of observations, a tentative mechanism has been proposed for the photocatalytic degradationof dye.
