Fabrication and structural characterization of porous tungsten oxide nanowires

This current work demonstrates the first reported successful synthesis of a novel unique one-dimensional nanostructure of monoclinic W18O49 that exhibits characteristic porous morphologies with the nanosized pores distributed rather regularly along the length of the nanowires. Their microstructures were characterized by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Raman spectrum. The unique porous structures may be helpful in studies of nanostructure growth mechanisms and find applications in numerous fields.
