Green synthesis of nickel oxide nanoparticles for photodegradation analysis

Abstract

The photocatalytic degradation activity of nickel oxide nanoparticles (NiO NPs) in polluted water is examined in this work. Plant-produced nanoparticles are more stable, and their synthesis rate is faster than that of other creatures. The NiO NPs were made at room temperature from Sargassum wightii extracted, and their bio-reducibility was investigated in depth. The formation, shape, structure, and other physicochemical features of the resultant NiO NPs were studied using a variety of experimental methods, such as X-ray diffraction (XRD), Field Emission scanning electron microscope (FE-SEM), High-Resolution Transmission electron microscopy (HR-TEM), DLS particle size analyzer, UV–VIS spectrophotometer and Fourier Transform Infrared (FT-IR) spectroscopy. The green synthesized NiO NPs were discovered to be potent catalysts for the breakdown of hazardous organic dyes such as Methyl Blue (MB), Reactive Red 120 (RR120), Methyl Orange (MO) in polluted water, especially when combined with reducing agents such as sodium borohydride.
