Title : Synthesis, charaterization and application of nano sized barium chromate for photocatalytic degradation of an organic pollutants
In the present investigation, nano-sized barium chromate has been used as a photocatalyst for the degradation of an organic pollutant. The semiconductor was prepared by precipitation method and it was characterized by different analytical techniques like XRD, SEM-EDS and FT-IR. Barium chromate absorbs major portion of visible light due to its yellow color and acts as an efficient photocatalyst. The effects of different operating parameters were studied to obtain optimum conditions for organic pollutant degradation. Physico-chemical parameters of the organic pollutant (before and after photocatalytic treatment) have also been studied to show the complete mineralization of organic pollutant molecules. A tentative mechanism for the photocatalytic degradation of organic pollutant has been proposed, where hydroxyl radical has been observed as an oxidizing species.
