摘要：

Among different type of transition metal oxides, tungsten trioxide (WO3) is a suitable candidate for electronic device fabrication due to its n-type property and wide band gap. Herein, one-dimensional tungsten trioxide (WO3) nanorods were achieved from an aqueous solution of sodium tungstate dihydrate (Na2WO4·2H2O) and sodium chloride (NaCl) in an acidic media by a time-optimized hydrothermal synthesis in autoclave at 180°C or different synthesis durations. For studying morphology and size of obtained powder, X-ray diffraction (XRD), scanning electron microscope (SEM), and high resolution transmission electron microscope (HRTEM) were applied. Finally, WO3 nanorods of about 2–3 μm in length and 100–200 nm in diameter were obtained during 3 h hydrothermal process.
