Abstract
Mn2P2O7 polyhedral particles were synthesized by simple and cost-effective method using manganese nitrate hydrate and phosphoric acid in the presence of nitric acid with further calcinations at the temperature of 800 °C. The crystallite size obtained from X-ray line broadening is 31 ± 13 nm for the Mn2P2O7. The X-ray diffraction and SEM results indicated that the synthesized nanoparticles have only the structure without the presence of any other phase impurities. The FT-IR and FT-Raman spectra show characteristic bands of the P2O74- anion. The UV-Vis-NIR spectrum confirms the octahedral coordination of Mn2+ ion. © 2009 Elsevier B.V. All rights reserved.
