Dendritic and tubular-like tungsten oxide nanostructures have been prepared by a one-pot approach using a natural cellulosic substance as template at different pH conditions. Analysis by X-ray diffraction and electron microscopy revealed tungsten oxide Na2W2O7 nanostructures having different morphologies according to the pH of the reaction, that is at pH=3, the morphology of tungsten oxide is dendritic structure; at pH 6 prepared tungsten oxide has tubular structure.
