Abstract

Nickel oxide nanoparticles have garnered significant attention due to their unique properties and versatile application in numerous fields ranging in catalysis, electronics, sensing, energy storage, and biomedical sciences. The production of NiO nanoparticles through green synthesis is increasingly recognized as an environmentally conscious substitute for the traditional synthesis approach. This review outlines (1) the utilization of biomaterial and plant extracts in the fabrication of NiO nanoparticles, along with the underlying mechanism; (2) the potential biological applications, including antimicrobial, anticancer, and antioxidant properties; (3) the photocatalytic capacity of NiO NPs for dye degradation and (4) as electrochemical and biosensor ability. The influence of synthesis parameters on the size, morphology, crystallinity, optical band gap, surface area, and stability of NiO NPs is examined, highlighting the importance of controlling these parameters for tailored properties. Overall, this review highlights the significant progress made in the synthesis, characterization, and applications of NiO NPs while addressing the challenges and future perspectives in this rapidly evolving field.
