В работе приведены результаты экспериментальных исследований по определению возможности повышения фотокаталитической активности диоксида титана за счет применения оксида вольфрама (VI), путем тестирования разложения родамина Б как органического загрязнителя в водных растворах под действием УФ-излучения, в том числе в видимом спектре. В качестве фотокатализаторов использовался промышленный диоксид титана рутильной модификации и триоксид вольфрама, полученный методом биологического синтеза за счет использования жизнедеятельности тионовых бактерий (Thiobacillus ferrooxidans). Установлено, что концентрация красителя в растворе со смесью TiO2 и WO3 в соотношении 1 : 1 под действием естественного солнечного излучения снизилась на 85 % после 28 дней исследования в сравнении с 30 % и 42 % для растворов с чистыми WO3 и TiO2 соответственно.

The paper presents the results of experimental studies to determine the possibility of increasing the photocatalytic activity of titanium dioxide through the use of tungsten (VI) oxide, by testing the decomposition of rhodamine B as an organic pollutant in aqueous solutions under the influence of UV radiation, including in the visible spectrum. Industrial titanium dioxide of rutile modification and tungsten trioxide obtained by biological synthesis due to the use of the vital activity of thionic bacteria (Thiobacillus ferrooxidans) were used as photocatalysts. It was found that the dye concentration in a solution with a mixture of TiO2 and WO3 in a ratio of 1: 1 under the influence of natural solar radiation decreased by 85% after 28 days of study compared with 30% and 42% for solutions with pure WO3 and TiO2, respectively.
