Description
  • Tungsten trioxide with the band gap about 2.58 eV is known as a material, which a photocatalytic effect after UV-radiation exposure can be observed. However, in some cases more detailed material specification and the consideration of its complex structural and stoichiometric uniqueness are lacked in its photoactivity data. The presented work is focused on the study of tungsten trioxide samples photoactivity using the unified method that determines the reference substances colour changes after 360 nm UV-radiation exposure. The samples were prepared by from ammonium paratungstate treated in oxygen or argon plasma, which was generated by capacitive coupled RF generator operated at low partial pressures. The differences in oxygen stoichiometry which depends on total temperature plasma, because especially the presence of hydrogen coming from the ammonium cation disintegration causes a partial reduction partly to the WO2.7 oxide.
