Large-scale hydrothermal synthesis of WO3 nanowires in the presence of K2SO4

Solvothermal synthesis and characterization of tungsten oxides with controllable morphology and crystal phase

“…One-dimensional (1D) tungsten oxides especially have attracted considerable interest due to their high aspect-ratio structure, large surface areas and unique physical properties, including optical, electronic characteristics and gas sensing effects [24][25][26]. Among the various synthesis methods of tungsten oxide nanoparticles, hydrothermal and solvothermal reaction processes have significant advantages, such as total control over their shape and size, low processing temperature, high homogeneity and so on [27][28][29]. Especially, the morphology of tungsten oxide could be effectively controlled by the solvothermal synthesis [29].…”

Since tungsten oxide compound has many crystal structures, the control of morphology and crystal phase maybe play important roles in achieving particular and excellent properties.…”

“…The sample annealed at 500°C will be identified hereafter as WB_500. C. An acid precipitation technique [12,13] …”

Synthesis, Characterization and Sensing Behavior of WO3 Nanocrystalline Powder for Toluene Vapor

“…In addition, metal oxides have been widely used as gas sensing materials for improving the performance of gas sensors [3,4]. Among these, tungsten oxide (WO 3 ) which is a wide band gap n-type semiconductor material is a potential candidate and has attracted considerable attention due to high sensitivity for reducing and oxidizing gases [5,6]. This paper deals with the synthesized WO 3 nanocrystalline powder by direct precipitation technique without surfactant and the sensing properties of the obtained nanomaterial toward different concentrations of toluene vapor.…”
