Синтезированные двойные системы были исследованы с помощью РФА, ИК спектроскопии, СЭМ, ПЭМ и ПЭМ-элементного картирования. РФА и ИК спектроскопия показали присутствие g-C3N4 в составе g-C3N4/NiS и g-C3N4/NiS2, однако присутствие сульфидов никеля обнаружено не было. СЭМ-анализ показал, что двойные системы имеют неоднородную структуру, плоские слои, наложенные друг на друга, а морфология частиц представлена неправильной формой и шероховатой поверхностью. ПЭМ доказала наличие слоев gC3N4 неправильной формы, а элементное картирование ПЭМ показало наличие азота, углерода, серы и никеля. Исследование фотокаталитического выделения водорода синтезированными образцами показало, что g-C3N4/NiS2 проявляет самую высокую скорость выделения водорода по сравнению с g-C3N4/NiS и g-C3N4. Таким образом, наибольшая скорость выделения водорода была достигнута для g-C3N4/NiS2 на 3-м часу облучения видимым светом, которая составила 56,79 μмоль/ч-1г-1.</p></abstract><trans-abstract xml:lang="en"><p>NiS and NiS2 co-catalysts were decorated on the surface of g-C3N4 through ion exchange reaction by precipitation method. Synthesized double systems were investigated using XRD, FT-IR, SEM, TEM, and TEM elemental mapping. XRD and FT-IR analyses showed the presence of g-C3N4 in the composition of g-C3N4/NiS and g-C3N4/NiS2, however the presence of nickel sulfides was not identified. SEM analysis showed that double systems have heterogeneous systems, the stacked flat sheets with wrinkles and an irregular shape morphology and rough surface, where the presence of irregular shape pores is visible. TEM proved the presence of irregularly shaped layers of g-C3N4, and TEM elemental mapping showed the presence of nitrogen, carbon, sulfur, and nickel. The ability of the photocatalytic hydrogen evolution by prepared samples revealed, that g-C3N4/NiS2 manifests the highest hydrogen evolution rate in comparison with g-C3N4/NiS and g-C3N4. Thus, the highest evolution rate of hydrogen was reached by g-C3N4/NiS2 on the 3rd hour of the visible light irradiation and was equal to 56.79 μmolh-1g-1.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>графитовый нитрид углерода</kwd><kwd>сульфид никеля</kwd><kwd>со-катализатор</kwd><kwd>фотокатализатор</kwd><kwd>выделение водорода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>graphitic carbon nitride</kwd><kwd>nickel sulfide</kwd><kwd>co-catalyst</kwd><kwd>photocatalyst</kwd><kwd>hydrogen evolution</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This research was funded by the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan (Grant № АР13068426).</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">Ozili P.K., Ozen E.
