Synthesis and characterization of manganese substituted cerium oxide nanoparticles by microwave refluxing method

Abstract

Nanocrystalline MnxCe1-xO2 (0 ≤ x ≤ 0.5) powders have been synthesized by microwave refluxing method. XRD, Raman spectroscopy and TEM analysis confirm the substitution of Mn in cerium oxide to a large extent. With increased Mn content, the crystallite size and lattice parameter found to be decreased. In addition, shifting of Raman main band towards lower frequency side was also observed with increased Mn. This could be attributed to the distortion of lattice of CeO2 due to the lattice strain induced by substitution of Mn. © (2015) Trans Tech Publications, Switzerland.
