Hydrothermal Synthesis and Characterization of Hexagonal Tungsten Trioxide
摘要
Abstract
Tungsten oxides inorganic semiconductor materials have been paid intensive attentions because of its unique physical and chemical properties as well as various applications including gas sensors, photocatalysis, photochromic devices,electrochromic devices and field emission. Hexagonal tungsten trioxide( h-WO3 ) was synthesized using hydro-thermal method through precursor of Na2 WO4·2H2 O by addition of Na2 SO4 . The structure and morphology of the samples were characterized by X-Rays Diffraction(XRD),field emission scanning electron microscopy(SEM),high resolution transmission electron microscopy( HRTEM) and Fast Fourier Transform( FFT) . Results show that hexagonal tungsten trioxide nanowires with 2.2 μm in length,85 nm in diameter can be obtained by using the heat treatment temperature of 160 ℃ for 12 h. Based on the HRTEM and FFT characterizations and crystal structure analyses, the growth direction of the tungsten oxide nanowires was determined along[001]direction with an inter-planar distance of 0.3880 nm.关键词
