Показано, что аккумулирующие фотокатализаторы TiO2:MoO3 являются полностью реверсируемыми и цикл фотозаряжение-генерация пероксида водорода может быть повторен многократно.</p></abstract><trans-abstract xml:lang="en"><p>   It has been shown using the chemiluminescence technique that in the case of TiO2:MoO3 composites, contrastingly to TiO2 photocatalysts, the process of superoxide photogeneration appears to be completely suppressed, whereas the photoelectron trapping in the MoO3 phase accompanied with the production of Mo(V) reduced states facilitates long-term generation of hydrogen peroxide that plays a role of biocide agent. It has been also shown that the TiO2:MoO3 accumulating photocatalysts are fully reversible and the cycle of photocharging followed by peroxide generation can be repeated many times.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хемилюминесценция</kwd><kwd>пероксид водорода</kwd><kwd>фотокатализ</kwd><kwd>диоксид титана</kwd><kwd>триоксид молибдена</kwd><kwd>реакция Фентона</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chemiluminescence</kwd><kwd>hydrogen peroxide</kwd><kwd>photocatalysis</kwd><kwd>titanium dioxide</kwd><kwd>molybdenum trioxide</kwd><kwd>Fenton reaction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственной программы научных исследований “Химические процессы, реагенты и технологии, биорегуляторы и биооргхимия” (подпрограмма “Химические технологии, процессы и реагенты”, задание 2.1.06.3, № гос. регистрации 20211572)</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the state research program “Chemical processes, reagents and technologies, bioregulators and bioorgchemistry” (subprogram “Chemical technologies, processes and reagents”, task 2.1.06.3, state registration No. 20211572)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">J.
