摘要：

Photocatalytic degradation of methylene blue was studied using ZnO nanopowders prepared through a green synthesis process. An aqueous solution of methylene blue was investigated in an open vessel equipped with sun light using ZnO nanopowders, as catalyst, with a concentration of 7.815 x 10(-6) M. ZnO nanomaterials, prepared through a green synthesis method, was characterized with XRD, FTIR, SEM, EDX and BET measurements. The photodegradation of methylene blue in terms of concentration change with respect to different time intervals was studied with the UV-vis spectroscopy. The mechanism for this photocatalytic degradation process has also been presumed.
