Synthesis and characterization of ZnO two-dimensional nanostructures: effect of hydrothermalgrowth time

Zinc oxide (ZnO) nanostructures have attracted attention mainly due to their unique properties such asdirect band gap in the UV-visible region and high binding energy at room temperature for various applicationsincluding photocatalysts. On the other hand, two-dimensional structures, due to their high effectivesurface area, provide many active sites for absorbing molecules as well as performing catalytic reactions.Zinc oxide cannot normally form into two-dimensional structures. But by controlling the growth conditionsand using surface coatings, it is possible to limit the growth of zinc oxide nanostructures along oneof the planes to obtain two-dimensional structures. In this article, using a simple hydrothermal method,we will make two-dimensional zinc oxide nanostructures and investigate the effect of the hydrothermalgrowth time parameter on the obtained structures. Also, we use X-ray diffraction (XRD) and scanningelectron microscopy (SEM) to characterize the fabricated nanosheets
