ABSTRACT: Chromium oxide nanoparticles were synthesized by the
reduction of potassium dichromate solution with Mukia Maderaspatana
plant extract. In electrochemical methods, Cr2O3 nanoparticles were synthesized by two ways, using platinum (Pt) electrodes and
K2Cr2O7 solution with H2SO4 as medium in the first case. And chromium doped platinum electrode (Pt/Cr) in
presence of NaHCO3 solution in second case. The resulting Cr2O3 nanoparticles were characterized by X-ray diffraction (XRD), Scanning electron microscopy
(SEM), UV-VIS absorption and Fourier-transform infrared (FTIR) spectroscopy.
The enhancing influence of Cr2O3 nanoparticles as a
catalyst for the decomposition of KMnO4 has been studied. The
antibacterial effect of Cr2O3 nanoparticles against E. coli was investigated. These particles
were shown to have an effective bactericide.
