Production and Photocatalytic Activities of ZnO Nanowire by Electrochemical Anodization

In this study, ZnO nanowires were grown on Zn sheet plates by electrochemical anodization using two different voltages (5V-10V). Following the growth process, the materail was heat treated at 300 ° C for 1 hour in the air to form the crystalline zinc oxide phase. The morphological and structural properties of the obtained structures were determined by scanning electron microscopy (SEM) and X-ray diffraction diffractometry (XRD), respectively. Finally, the photocatalytic performance of ZnO nanowires was tested on aqueous methylene blue solutions. An increase in nanowire formation was observed with increased voltage in the grown structures. It was determined that the structure obtained by anodizing and heat treatment is in the ZnO nanowire structure. As a result of photocatalytic tests, The highest photocatalytic degradation rate was determined as 112x10-3 sa-1 in the growth structures with 10V anodization voltage
