Li_2MoO_3のディインターカレーション

概要

Chemical deintercalation of lithium ions was attempted on Li_2MoO_3, with a structure related to the α-NaFeO_2, type structure. The lithium ions in Li_<2-x>MoO_3 were removed up to x = 0.77 by oxidation, and its structure remained almost unchanged. The evolution of the lattice parameters for deintercalation compounds was divided into two parts ; the regions of O <x≦0.51 and 0.51 <x≦0.77. In the first region, both α-and c-axes increased with an increase of x. In the second region the a-axis increased with increasing x, while the c-axis remained unchanged. This behavior could be explained by the existence of Mo-Mo bonding and immigration of lithium ions from the ( (Ll_<1/3>Mo_<2/3>) O_2) n layer to the interlayer spaces. Magnetic properties of Li_<2-x>MoO_3 exhibited temperature-independent paramagnetism.
