Abstract

Nano-sized silver doped Mn2O3 was synthesized by starch assisted co-precipitation technique. The prepared samples were tested for CO oxidation reaction. Ag doped Mn2O3 sample was found to show higher activity then pristine Mn2O3. XRD patterns authenticate the formation of Mn2O3 phase. Electron microscopy images show that the particles are in nano-sized, agglomerated and 40 - 70 nm in range. Thermal analysis data indicates the phase change from Mn2O3 to Mn3O4 beyond 950 oC. Magnetic susceptibility data indicates the paramagnetic nature of these samples. Electrical resistivity measurement shows that these samples are semiconductors.
