Композиты получены методом электроспиннинга и двухстадийной термической обработки, состоящей из пре-окисления и карбонизации, из смеси поливинилпирролидона (ПВП), дигидрата хлорида олова (SnCl2⋅2H2O) и фосфорной кислоты в растворе этанол:H2O. Физикохимические свойства полученных нановолокон были изучены с помощью рентгеновской диффракции, сканирующей электронной микроскопии (СЭМ) и элементного анализа CHNS. Массовое соотношение SnCl2⋅2H2O:ПВП, температура предварительного окисления и время отжига определяли фазовый состав и морфологию нановолокон. В образцах, прокаленных при 900°C в течение 10 мин, наблюдалась высокая кристалличность, образование фазы SnP и испарение фосфора, что способствовало формированию градиентной структуры. По результатам СЭМ было выявлено, что диаметр волокон зависит от массовой доли SnCl2⋅2H2O. Повышение температуры предварительного окисления приводило к окислению углерода и образованию аморфной структуры. Таким образом, регулирование условий отжига позволяет контролировать структурные свойства углеродных композитных нановолокон. Эти материалы могут быть перспективными анодными материалами для энергонакопительных систем с высокой производительностью.</p></abstract><trans-abstract xml:lang="en"><p>In this study, the structural and morphological changes of carbon composite nanofibers based on tin phosphide/phosphate were investigated depending on the synthesis conditions. The composites were obtained through electrospinning and two-step thermal treatment, comprised of pre-oxidation and carbonization, from a mixture of polyvinylpyrrolidone (PVP), tin chloride dihydrate (SnCl2⋅2H2O), and phosphoric acid in ethanol: H2O solution. The physical-chemical properties of the resultant nanofibers were studied by X-Ray diffraction, scanning electron microscopy (SEM), and CHNS elemental analyzer. The mass ratio of SnCl2⋅2H2O:PVP, the pre-oxidation temperature, and the annealing time determined the phase composition and morphology of the nanofibers. Samples annealed at 900°C for 10 min exhibited high crystallinity, the formation of the SnP phase, and phosphorus evaporation, which contributed to the development of a gradient structure. SEM results showed that the fiber diameter depended on the mass fraction of SnCl2⋅2H2O. An increase in the pre-oxidation temperature led to carbon oxidation and the formation of an amorphous structure. Thus, by adjusting the annealing conditions, the structural properties of carbon composite nanofibers can be controlled. These materials have the potential to serve as promising anode materials for high-performance energy storage systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нанокомпозит</kwd><kwd>фосфид олова</kwd><kwd>нановолокна</kwd><kwd>электроспиннинг</kwd><kwd>термообработка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Nanocomposite</kwd><kwd>tin phosphide</kwd><kwd>nanofibers</kwd><kwd>electrospinning</kwd><kwd>thermal treatment</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">One-dimensional mesoporous inorganic nanostructures and their applications in energy, sensor, catalysis and adsorption / H.
