WO_3 nanowires were fabricated by a hydrothermal method,which proceeded at 170 ℃ for 48 h in a solution containing C_2H_(10)N_6H_2SO_4 as a dispersant and Na_2WO_4 as a starting material.The nanowires exhibit a well crystallized one-dimensional structure with 20 nm in diameter and several microns in length.The physicochemical properties of WO_3 were compared using X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),energy dispersive X-ray spectroscopy(EDX) and UV-vis spectroscopy(UV-Vis).The photoactivity of the as-perpared WO_3 nanowires was evaluated through the photodegradation of methylene blue(MB) in aqueous solution.The experimental results demonstrate that addition of C_2H_(10)N_6H_2SO_4 salt in the WO_3 nanowires synthesis process can enhance its photocatalytic activity obviously.
