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 × 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
