Одной из актуальных задач является простой и контролируемый синтез материалов на основе халькогенидов переходных металлов (в частности, MoSx), способных проявлять повышенную каталитическую активность в реакции выделения. В работе путем варьирования лазерного флюенса и давления буферного газа созданы пленки MoSx, различающиеся химическим состоянием на фотоактивном слое WSe2. Определены режимы осаждения пленок, в результате которых получены каталитические слои с минимальным содержанием субстехиометрических состояний, ответственных за смещение уровня Ферми ко дну запрещенной зоны. Объединив экспериментальные результаты по измерению фототоков и расчеты методом DFT определены каталитически активные участки поверхности пленок MoSx.</p></abstract><trans-abstract xml:lang="en"><p>Method of pulsed laser deposition (PLD) has attracted increasing attention as a promising approach for optimizing catalysts to enhance their efficiency in various applications. One of the current challenges is the simple and controllable synthesis of materials based on transition metal chalcogenides (in particular, MoSx), which can exhibit an increased electrocatalytic activity in the hydrogen evolution reaction. Changes in the chemical states of sulfur and molybdenum as a result of photo-electrochemical tests are studied in this work. By varying the laser fluence and buffer gas pressure, deposition regimes have been determined, resulting in catalytic layers with minimal sub-stoichiometric states, which are responsible for shifting the Fermi level to the conduction band edge. Combining experimental results and DFT calculations, catalytically active sites on the film surfaces have been identified.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>импульсное лазерное осаждение</kwd><kwd>халькогениды переходных металлов</kwd><kwd>реакция выделение водорода</kwd><kwd>кластеры</kwd><kwd>каталитически активные участки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pulsed laser deposition</kwd><kwd>transition metal chalcogenides</kwd><kwd>hydrogen evolution reaction</kwd><kwd>clusters</kwd><kwd>catalytically active sites</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования РФ в рамках госзадания на НИР (проект FSWU-2023-0070).</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">Li B., Jiang L., Li X., Cheng Z., Ran P., Zuo P., Qu L., Zhang J., Lu Y. // Adv.
