Synthesis, Characterization, and Lithium Storage Capabitity of AMoO4 (A = Ni, Co) Nanorods

One-dimensional (1D) AMoO(4)center dot nH(2)O (A = Ni, Co) nanorods have been synthesized by a facile hydrothermal method. The effect of different synthetic conditions on the morphologies of the Final products was systematically investigated. The size of the nanorods can be easily controlled by adding ethanol in the synthetic solution. For the first time, the self-assembled growth of oriented NiMoO4 center dot nH(2)O nanorod arrays on Ti-foil substrates was achieved. The thermal dehydration and phase transformation processes of AMoO(4)center dot nH(2)O nanorods were thoroughly investigated by TG-DTA and time-resolved synchrotron XRD. As-prepared hydrate nanorods can be further converted to corresponding AMoO(4) nanorods by annealing at 300-600 degrees C for 1 h without significant alteration of 1 D morphology. Electrochemical lithinum storage capabilities of dehydrated AMoO(4) nanorods have been investigated. The results Suggest their potential use as cathode materials for lithium ion batteries.
