Facile Synthesis of Polymer Capped NiO Nanoparticles, Characterization, Photocatalytic and their Antibacterial Activities

Abstract

In the field of nanotechnology, the creation of efficient and efficient procedures for the synthesis of nanoparticles was important. The field of nanotechnology focused on the creation and application of devices and structures with organisational characteristics between the size of a single molecule and around 100 nm, where unique qualities emerge in contrast to bulk materials. The biological applications of nickel oxide include the enhancement of magnetic resonance imaging, the storage of magnetic data and the purification of biological samples using ferrofluids for catalysis, drug delivery, sensors and pigments. In this study, a new inorganic (NIO) nanoparticle's potential photocatalytic and antibacterial activities were examined. A straightforward chemical process was used to effectively produce nickel oxide nanoparticles. Polyvinyl alcohol serves as a polymer capping agent. The structure morphology and crystalline phase of NiO nanocrystals were investigated by XRD, SEM and TEM. The optical study was investigated by FT-IR spectroscopy. The anti-microbial activity of nanoparticles was determined by Gram-positive and Gram-negative bacteria.
