Abstract
Herein, we synthesis ZnO nanosheets via facial hydrothermal method using sodium hydroxide (NaOH) as a stabilizer.
The synthesized ZnO was subjected to various characterizations for analysis of their optical, structural, functional groups, chemical composition, surface morphological and thermal studies, obtained results reveals the following features; UV-Vis spectroscopy analysis shows absorption maximum at 272 nm which confirms the preliminary presence of ZnO material.
X-ray diffraction (XRD) analysis reveals the average crystalline grain size is found to be of around 38.10 nm. Fourier transform infrared spectroscopy (FT-IR) analysis reveals the presence of O-H, C-H, C-N and Zn-O bands. Atomic force microscopy (AFM) and scanning electron microscopy analysis (SEM) shows the topological structure of ZnO and it having nanosheets like nature. Energy dispersive X-ray spectroscopy (EDS) analysis confirms the chemical compositions were Zn and O elements. Further, we observed by thermo gravimetric analysis (TGA) that for synthesized ZnO nanosheets weight loss is of 15.574% was occurred at 47.49˚ C to 300˚ C. After 300˚C, none of the materials underwent greater than 1% of weight loss. From DSC analysis, we observed that there are endothermic reactions in between 23˚C to 500˚C. In addition, we proposed to study biological activities of these synthesized ZnO nanosheets. Copyright © 2018 VBRI Press
