Abstract: [eng] [cze]
By decomposition of ammonia paratungstate in a radiofrequency generated oxygen or argon plasma, a series of specimens with the following stoichiometry were prepared: WO3, WO2.98, WO2.90 and WO2.82. The product structure was characterized by X-ray diffraction, oxygen content by the fussion extraction method (LECO) and TGA. Photocatalytic activity was determined by measuring the color change of spectrophotometric indicators. Rozkladem parawolframanu amonného v radiofrekvenčním kapacitně buzeném kyslíkovém nebo argonovém plazmatu byla připravena serie vzorků oxidů wolframu s různou kyslíkovou stechiometrií: WO3, WO2.98, WO2.90 and WO2.82 . Produkty byly charakterizovány rentgenostrukturní analýzou, termogravimetricky a měřením obsahu kyslíku fúzní extrakcí na přístroji LECO. Fotokatalytická aktivita byla určována z barevných změn spektrofotometrických indikátorů.
