Journal Article 2024 03 01 A novel zinc oxide - agar nanocomposite was successfully synthesized using zinc chloride as a precursor. The nanocomposite was prepared using a domestic microwave oven. The prepared nanocomposites have been characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and UV- visible spectroscopy. The crystalline properties of the synthesized materials were investigated by XRD and Raman spectroscopy. The UV- visible spectra shows a characteristic the absorption peak at 356 nm. The morphological observation of the SEM results reveals that the ZnO nanostructures are between 50 to 100 nm in size, and are embedded in the agar matrix.
