Synthesis and characterization of a pipe-structure manganese vanadium oxide by hydrothermal reaction
Abstract
A novel manganese vanadium oxide has been synthesized using the hydrothermal reaction of vanadium(V) pentoxide with manganese(II) sulfate with an organic templating cation at 165 °C. The (Mn2+)6(Mn3+)1–2/3z- (OH)3(VO4)3[(VO4)1–2z(V2O7)z] (z = 0.2) phase has a hexagonal tunnel structure and space group P63mc. The cell parameters of this compound are a = 13.229(1) and c = 5.255(1) Å. This compound was also characterized by electron microprobe analysis, FTIR, TGA as well as electrochemically and reacted readily with lithium in electrochemical cells.
