Abstract

An endeavor has been made to report the green synthesis of Fe doped chromium oxide nanoparticles using nigella sativa seed extract as reducing and capping agent. The synthesized nanoparticles were characterized by using XRD, EDS, DLS, AFM analysis, UV-DRS, FTIR spectroscopy, and SEM analysis to check the behavior in visible light. Crystalline structure of Cr2O3 nanoparticles were forced to deposit Fe onto the surface. By using cyclic voltammetry (CV) investigation and EIS analysis, the electrochemical behaviour and specific capacitance of the Fe doped Cr2O3 nanoparticles electrode were examined. The antibacterial activity of chromium oxide nanoparticles was tested against Staphylococcus aureus, Klebsiella pneumonia and Pseudomonas aeruginosa. The photocatalytic degradation of biosynthesized Cr2O3 nanoparticles was evaluated by degrading methylene blue dye and Congo red dye while being exposed to the visible light.
