Chromium oxide nanoparticles (NPs) have been rapidly synthesized by precipitation method using ammomia as precipitating agent and are characterized by using X-ray Diffraction (XRD), Thermo Gravimetric Analysis (TGA), UV-Visible absorption (UV), Infrared Spectoscopy (IR), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). XRD studies show that chromium oxide NP is formed as Cr 2 O 3 and it has hexagonal structure. The shape and particle size of the synthesized Cr 2 O

UV-Visible absorption and IR spectoscopy confirm the formation of nanosized Cr 2 O 3 . TGA verifies that the Cr 2 O 3 NPs are thermally stable upto 1000 °C.
