Visible li ght degra dation of methylene blue using Sb-dop ed ZnO n anostructu res prepared under m icrowave irradiati on

Photodegradation of org anic pollut ants for wat er treatment has attracted wide att ention due to its e ffectiveness , easy operation and id eally produ cing nonto xic products [۱]. ZnO is of interest as a p hotocatalyst in the degradation of environmental pollutants [۲]. To expand the usage of this p hotocatalyst, many stu dies employed modifications onto Z nO nanopar ticles in ord er to improve its c atalytic efficiency thro ugh enhancements of absorbance in the visible-light region [۳]. In this work, we have prepared Sb-do ped ZnO nanostructure s in water by microwave irradiations and effects of some operational param eters on photocatalytic activity were investigate d.
