Synthesis and structural characterization of copper incorporated manganese oxide OMS-2 materials synthesized via potassium birnessite

Metal ion incorporated tunnel structured manganese oxide OMS-2 has been recently exploited as potential materials in the field of heterogeneous catalysis Cryptomelane type copper incorporated manganese oxide OMS-2 type tunnel structured material has been synthesized by hydrothermal method using birnessite-containing potassium as a parent precursor instead of using birnessite containing sodium. Crystal structure and thermal stability of as synthesized materials are characterized by using XRD and TGA. Surface area and morphology of newly synthesized copper incorporated OMS-2 type materials have been studied by BET and SEM analyses. (c) 2006 Elsevier B.V. All rights reserved.
