Study nanostructueres of semiconductor zinc oxide (ZnO) as a photocatalyst for the degradation of organic pollutants in water and wastewater

In the present study, Comparison of photocatalytic activity of nanostructueres semiconductor zinc oxide (ZnO) were prepared using the different method on the degradation of organic dye such as methylene blue that was investigated. Previous studies have proved that such semiconductors can degrade most kinds of persistent organic pollutants, such as detergents, dyes, pesticides and volatile organic compounds, under UVirradiation. in some observed reports the photocatalytic activity of the coupled photocatalysts, evaluated by using organic dyes photodegradation as a probe reaction in the different coupled photocatalysts which increases the activity of photocatalytic.In this survey ,activity of ZnO nanostructures and ZnO nanocrystalline, for degradation of methylene Blue is different.also the rate of operation photocatalysts ZnO nano composites on the organic dye is different too. measurment Catalyst characteristics were obtained by BET, XRD, TEM, AFM, Raman and FTR-IR spectroscopy.
