A low-cost, a high-yielding of vanadium oxide nanobelts 2 was simply synthesized by hydrothermal treatment of our (NH₄)₂V₃O₈, 1, with deionized water at 200 �°C for 3 days. The SEM observations show that ribbon-like nanobelts are about 150-300 nm wide and thousands of nanometers long. The XRD pattern reveals a set of the paper form reflections, characteristic of (00l) reflections for layered phases. Based on FT-IR results and the EDX spectra, the chemical formula of the as-obtained ribbon-like nanobelts could be described as V_xO_y.nH₂O with a mixed valence V(V) and V(IV).
