Текстурные свойства упорядоченного нанопористого кремнезема, синтезированного на мезогенном темплате
Разработано несколько путей синтеза и исследованы корреляции между переменными процедуры синтеза и физико-химическими свойствами нанопористых кремнеземных материалов типа MCM-48, осаждаемых темплатным методом в присутствии низковалентного катиона железа(II). Изучено изменение структуры мезопористого каркаса кремнезема, его текстурных свойств и степени энергетической неоднородности поверхности в зависимости от молярного соотношения Fe :Si, значения рН (4 и 9 единиц), ступенчатого прокаливания (673 и 923 К) и экстракции цетилпиридиниевого темплата этанолом из ксерогелей.
