Phytogenic Synthesis and Characterization of NiO-ZnO Nanocomposite for the Photodegradation of Brilliant Green and 4-Nitrophenol

The NiO-ZnO nanocomposite (NiO-ZnO NC) was synthesized by ecofriendly process using Diospyros kaki (D. kaki) extract of leaves as reducing and capping agents. X-ray diffraction (XRD) used for examined crystallinity, cell dimensions, crystallite size (7.6 nm). To determine the purity sample weight percentage, energy dispersive (EDX) is used. surface morphology determined scanning electron microscopy (SEM) transmission (TEM). By Fourier transform infrared spectroscopy (FTIR), functional groups in samples were determined. diffuse reflectance data (DRS), band gap calculated via Tauc plot 3.23 eV. photocatalytic activity checked against brilliant green (BG) 4-nitrophenol (4-NP) 92.5% 69.7% degraded with rate degradation which 0.0281 0.011 min−1.
