Abstract

A flower like ZnO nanostructures are synthesized using by a novel chemical method without using any precipitating agent. Structural, morphological and optical properties are studied using powder XRD, FE-SEM, TEM and UV–Vis. spectroscopy measurements. The synthesized flower like ZnO nanostructures are in single hexagonal wurtzite phase with good crystalline nature. The average size of the flower like ZnO nanostructures is 50 nm visualized from FESEM images, which composed of 5 nm ZnO spherical nanoparticles. The formation mechanism for a flower like ZnO nanostructures are discussed in detail. Optical absorption spectrum of ZnO nanoflower showed a band gap of 3.25 eV. Photoelectrochemical water splitting performance is evaluated by current density measurement for different applied voltage. The improved photocurrent density is shown as 0.39 mA/cm at 0.6 V versus Ag/AgCl under simulated solar irradiation.
