Title: The Effect of Silver Ion Occupancy on Hollandite Lattice Structure

Abstract

ABSTRACT The effect of tunnel cations on tunnel size in α-MnO 2structured (hollandite, cryptomelane) materials has long been of interest, as the tunnel size effects catalytic and transport properties. Previous research on the tunnel size has focused on potassium cryptomelane (K xMn 8O 16). This paper uses synthetic control of silver content in Ag xMn 8O 16to investigate the effect that tunnel silver occupancy has on the lattice parameters. Materials with silver (x) content between 1.14 and 1.66 were synthesized, synchrotron diffraction and Rietveld Refinement was used to determine lattice parameters. The lattice parameters were found to contract as silver content increases (from 9.774 Å to 9.738 Å), in contrast to previous investigations of other tunnel cations.
