Hydrazine monohydrate adsorbs on catalysts, both active and inactive, in the infrared region of the spectrum. The location of the particles of adsorbed hydrazine monohydrate is on the carrier. There was no correlation found between the spectral features on several of the catalysts studied and their catalytic activity in hydrogen formation. The main transformation reactions occur in the metallic phase of the supported catalysts. It was found that, due to the reaction energy, the size and structure of the clusters were reduced and rearranged to create centers suitable for the effective course of intramolecular dehydrogenation of hydrazine. At the same time, this process was most effective on smaller clusters, possibly because a stronger Me-H bond was formed on them. Adsorption of hydrazine monohydrate through hydrogen atoms was possible on these clusters. These conditions ensured the predominant formation of hydrogen at low temperatures. An increase in temperature contributed to the course of a competing reaction of ammonia formation, associated with the breaking of the N-N bond in the adsorption complex. As result, the formation of NH<sub>2</sub> complexes is taking place, and then ammonia.</p></abstract><trans-abstract xml:lang="ru"><p>C помощью комплекса физико-химических методов изучено взаимодействие моногидрата гидразина с никелем на разных носителях. Моногидрат гидразина адсорбируется на катализаторах как в активной, так и в неактивной в ИК-области спектра формах. Местом локализации частиц адсорбированного моногидрата гидразина является носитель. Корреляции между спектральными проявлениями для ряда исследуемых катализаторов и их каталитической активностью в образовании водорода не обнаружено. Активированные за счет адсорбции на носителе поверхностные комплексы гидразина диффундируют на кластеры, где проходят основные реакции образования водорода. Обнаружено, что за счет энергии реакции происходит уменьшение размера и, по-видимому, перестройка структуры кластеров с появлением центров, подходящих для эффективного протекания внутримолекулярного дегидрирования гидразина. Наиболее эффективно процесс проходит на кластерах меньшего размера, возможно, за счет того, что на них возникает более прочная связь Me-H. На кластерах возможна адсорбция моногидрата гидразина через атомы водорода. Эти обстоятельства обеспечивают преимущественное образование водорода при низкой температуре. Повышение температуры способствует протеканию конкурентной реакции образования аммиака, связанной с разрывом связи N-N в адсорбционном комплексе, что приводит к возникновению комплексов NH<sub>2</sub> и затем аммиака.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hydrogen</kwd><kwd>hydrazine</kwd><kwd>hydrazine monohydrate</kwd><kwd>intermediates</kwd><kwd>IR spectroscopy in situ</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>превращение моногидрата гидразина</kwd><kwd>водород</kwd><kwd>промежуточные соединения</kwd><kwd>молекулярная спектроскопия in situ</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>075-03-2025-092</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hydrogen and other Alternative Fuels for Air and Ground Transportation.
