Synthesis of Vanadium-Doped Nano-Sized WO3 by a Combination of Sol–Gel Process and Hydrothermal Treatment

The synthesis of nano-sized oxide WO 3 –25 at % VO 2 by a combination of sol–gel process and hydrothermal treatment using metal alkoxoacetylacetonates as precursors was studied. The synthesis gave the oxide powder isomorphous to hexagonal tungsten(VI) oxide. The thermal behavior of the powder in an...

Description
Summary:The synthesis of nano-sized oxide WO 3 –25 at % VO 2 by a combination of sol–gel process and hydrothermal treatment using metal alkoxoacetylacetonates as precursors was studied. The synthesis gave the oxide powder isomorphous to hexagonal tungsten(VI) oxide. The thermal behavior of the powder in an air flow was studied by simultaneous thermal analysis in the temperature range of 25–600°C. The resulting particles were shaped as nanorods. Using Kelvin probe force microscopy, the electron work function of the material surface was determined.
