VO x .nH 2 O (2.0=<x=<2.5) nanoribbons have been synthesized by direct hydrothermal processing of the aqueous solution of NH 4 VO 3 and polyethylene glycol 400 (PEG-400) at pH 3.5-5.5. Techniques of XRD, SEM, TEM, HRTEM, ED, and XPS have been used to characterize the structure, morphology, and composition of the nanoribbons. The VO x .nH 2 O nanoribbons...
