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.
