INTRODUCTION
Scanning electron microscopy
Ø A simple and conventional method for the synthesis of the ZnO
(A)
Nanoparticles like Nanolotus and Nanoflakes for further these synthesized NPs using as a Photocatalyst in water splitting and organic pollutant degradation reactions.
ØThe structure and morphology of the formation of ZnO nanoparticles
A. FESEM image of ZnO Nanoparticles like Nanoflakes
like Nanolotus and Nanoflakes was evidenced by UV-Vis, X-ray diffraction, FTIR and energy-dispersive spectroscopy techniques. The size, shape of metal like Nanolotus and Nanoflakes nanoparticles was systematically investigated by SEM analysis.
(B)
Ø The photo response of the prepared samples has been explored by using a model reaction for Eco-friendly Hydrogen Production.
