Комплексное изучение влияния процесса активации на морфологические, структурные и элементные характеристики технического углерода для создания функциональных углеродсодержащих материалов с заданными свойствами.</p></sec><sec><title>   Методы</title><p>   Методы. Морфология поверхности и дисперсность исследованы методом сканирующей электронной микроскопии (JEOL 6610LV, детектор вторичных электронов, 20 кВ, увеличение до ×100 000). Локальный элементный состав определялся энергодисперсионным анализатором (Oxford Instruments) с картированием элементов. Конфокальная лазерная микроскопия (OmegaScope AIST-NT, разрешение до 300 нм) применялась для анализа формы, размеров и агрегации частиц. Кристаллохимический анализ проводился методом рентгенофазового анализа (EMMA, CuKα, λ = 1,5406 Å, диапазон 2θ = 10 – 80°). Структурные дефекты и функциональные группы идентифицировались методом спектроскопии комбинационного рассеяния света (лазер λ = 532 нм, спектральное разрешение 3 см-1).</p></sec><sec><title>   Результаты</title><p>   Результаты. Установлено, что процесс активации приводит к значительной трансформации структуры технического углерода. Наблюдается уменьшение среднего размера частиц с ~3 мкм для пиролизного углерода до ~2 мкм для активированной формы, сопровождающееся снижением коэффициента полидисперсности с 1,2 до 0,3, что свидетельствует о сужении распределения частиц по размерам. Процесс активации обеспечивает равномерное внедрение кремния в углеродную матрицу с достижением концентрации до 3,2 ат. %, способствуя формированию гомогенной нанокомпозитной структуры углерод – кремнезем. Одновременно происходит структурное упорядочение углеродного компонента с достижением параметров, характерных для графита c межслоевым расстоянием d002 = 0,3354 нм.</p></sec><sec><title>   Заключение</title><p>   Заключение. Активация технического углерода позволяет целенаправленно формировать упорядоченные углерод-кремнеземные нанокомпозиты с развитой поверхностью и контролируемой дефектностью, перспективные для применения в сорбционных процессах и катализе.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Purpose</title><p>   Purpose. Comprehensive study of the effect of the activation process on the morphological, structural, and elemental characteristics of technical Carbon in order to create functional carbon-containing materials with specified properties.</p></sec><sec><title>   Methods</title><p>   Methods. Surface morphology and dispersity were investigated by scanning electron microscopy (JEOL 6610LV, secondary electron detector, 20 kV, magnification up to ×100,000). Local elemental composition was determined by energy-dispersive X-ray analysis (Oxford Instruments) with element mapping. Confocal laser microscopy (OmegaScope AIST-NT, resolution up to 300 nm) was used to analyze particle shape, size, and aggregation. Crystallochemical analysis was carried out by the method of rethgenophase analysis of X-ray diffraction (EMMA, CuKα, λ = 1.5406 Å, 2θ range = 10 – 80°). Structural defects and functional groups were identified by the method of Raman scattering spectroscopy (laser λ = 532 nm, spectral resolution 3 cm-1).</p></sec><sec><title>   Results</title><p>   Results. It has been established that the activation process leads to a significant transformation of the technical Carbon structure. There is a decrease in the average particle size from ~3 μm for pyrolytic Carbon to ~2 μm for the activated form, accompanied by a decrease in the polydispersity coefficient from 1.2 to 0.3, which indicates a narrowing of the particle size distribution. The activation process ensures the uniform incorporation of silicon into the Carbon matrix, reaching a concentration of up to 3.2 at. %, resulting in the formation of a homogeneous Carbon-silica nanocompositestructure. At the same time, the Carbon component is structurally ordered, reaching the parameters characteristic of graphite with d002 = 0.3354 nm.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. Activation of technical carbon allows for the purposeful formation of ordered Carbon-silica nanocomposites with a developed surface and controlled defectiveness, which are promising for use in sorption processes and catalysis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>технический углерод</kwd><kwd>активация</kwd><kwd>пиролизный углерод</kwd><kwd>морфология</kwd><kwd>рентгенофазовый&#13;
