Hexagonal Tungsten Trioxide Nanowire 667

Hexagonal tungsten trioxide nanowire may be synthesized by hydrothermal method using Na2WO4?2H2O and HCl as raw materials, K2C2O4 and K2SO4 as structure-directing agents respectively. The hydrothermal reaction was conducted at 150°C for 12h. The structure of hexagonal WO3 nanowire obtained presents complex net structure with higher specific surface area, which improves the photocatalytic activity of the material. The presence of two additives, K2C2O4 and K2SO4, proved that K+ plays an important role in guiding the growth of WO3 nanowire. The…
