Синтез наноструктурированных композиционных материалов MoO₃/TiO₂–SiO₂ сферической формы, приготовленных на основе смол

Целью работы являлся синтез наноструктурированных композитов MoO₃/TiO₂–SiO₂ полой сферической формы путем термического разложения анионообменников, насыщенных ионами Mo₇O^6-₂₄ и обработанных золем ТБТ–ТЭОС. Показано влияние кинетики (метод Киссинджера и Метцгера-Горовица) термического разложения смол пористой и гелевой структур на размер наночастиц MoO₃ и прочность сфер MoO₃/TiO₂–SiO₂. Образованию плотных сферических наноструктурированных агломератов композита способствуют реакции, протекающие на границе раздела фаз цилиндрической и сферической симметрии при использовании анионообменной смолы с пористой структурой. Реакции разложения анионообменной смолы гелевой структуры, сопровождающиеся случайным зародышеобразованием, приводят к образованию полых сферических агломератов композита с трещинами на поверхности. Материалы были охарактеризованы методами ДСК-ТГА, РФА и СЭМ.
