Description	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
