Spectroscopic characterisation and antibacterial activity of ZnO nanosheets

This paper describes an easy synthesis of zinc oxide (ZnO) nanosheets using triethylamine (TEA) as a complexing agent with zinc sulphate hexahydrate as a zinc source. The as-formed zinc triethylamine complex was calcined at 600 °C for 6 h to get ZnO nanosheets. The synthesised sample was characterised by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), UV-visible (UV-Vis), energy dispersive X-rays (EDS) spectroscopy, scanning electron microscopy (FESEM) and high resolution transmission electron microscopy (HR-TEM). The antibacterial activity of ZnO nanosheets was evaluated using agar diffusion method. The results suggest that the synthesised ZnO nanosheets will be a promising candidate in the field of biomedical application.
