Abstract

In this study, we explore the magnetic and optical properties of nickel nanoparticles decorated with chitosan/hybrid ceria (iron doped ceria) alongside their potential use in the photodegradation of rhodamine B dye. To support our experimental results, we use Density Functional Theory (DFT) analysis. In addition, the antibacterial activity of the synthesized nanocomposite is evaluated. The hybrid nanoparticles have interesting magnetic and optical characteristics, which make them a viable option for a variety of applications. The chitosan hybrid ceria-nickel nanoparticles also successfully photodegrade the dye rhodamine B, suggesting their potential uses in environmental remediation. Additionally, the nanocomposite antimicrobial activity against the gram-positive Streptococcus pneumoniae and gram-negative Klebsiella pneumonia, which cause a variety of diseases including pneumonia, urinary tract infection, sinusitis, osteomyelitis, meningitis, and septic arthritis, was evaluated demonstrating the nanocomposite ability to fight infectious infections. Overall, this paper thoroughly evaluates the nickel nanoparticles supported on the chitosan hybrid ceria, emphasizing their various features and prospective uses.
