Abstract

Synthesis of a 1D structural nanowire of V2O4· 0.25H2O starting from V2O4 particles by a soft chemical process, using only the raw material and water, was described. A formation mechanism for the nanowires was proposed according to the scanning electron microscopy, transmission electron microscopy and X-ray diffraction measurements. A route, which involves no catalysts and requires no expensive equipment, will offer great opportunities for the scale-up preparation of 1D nanostructured materials. Electrochemical measurements indicated that an electrode of V2O·0.25H2O nanowires shows reversible intercalation of lithium ions into/out of the layered matrix.
