Фазовый состав катализаторов варьировали путем изменения температуры прокаливания диоксида титана. Физико-химические свойства образцов исследовали методом рентгенофазового анализа, спектроскопии диффузного отражения, просвечивающей электронной микроскопии, энергодисперсионного анализа, циклической вольтамперометрии, хроноамперометрии с периодическим освещением. Каталитическую активность образцов изучали в реакции фотокаталитического разложения аммиака. Было показано, что с ростом количества анатаза в образце увеличивается каталитическая активность выделения водорода. Данная закономерность напрямую связана с положением края зоны проводимости анатаза и рутила. Наибольшая каталитическая активность выделения водорода составила 324 мкмоль·ч–1·г–1.</p></abstract><trans-abstract xml:lang="en"><p>In this work titania with different ratio of anatase and rutile was synthesized. The phase composition of the samples was varied by changing temperature of calcination. The physico-chemical properties of the samples were studied by X-ray diffraction, diffuse reflectance spectroscopy, transmission electron microscopy, energy-dispersive X-ray analysis, cyclic voltammetry, on-off curves. The catalytic activity of the samples was examined in the photocatalytic ammonia decomposition. It was shown that the catalytic activity of hydrogen formation increased with the anatase content. The highest value of the catalytic activity was 324 μmol h-1g-1.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотокатализ</kwd><kwd>разложение аммиака</kwd><kwd>выделение водорода</kwd><kwd>диоксид титана</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photocatalysis</kwd><kwd>ammonia decomposition</kwd><kwd>hydrogen evolution</kwd><kwd>titania</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование фотокатализаторов методами СДО, ПЭМ и СЭМ проведено с использованием оборудования ЦКП «Национальный центр исследования катализаторов».
