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.
