ТЕОРЕТИЧЕСКОЕ ИССЛЕДОВАНИЕ ВЛИЯНИЯ РЯДА ТЕРМОДИНАМИЧЕСКИХ И КИНЕТИЧЕСКИХ ФАКТОРОВ НА ОСОБЕННОСТИ РОСТА НАНОРАЗМЕРНЫХ ЧАСТИЦ ДВУОКИСИ ТИТАНА

Аннотация


Проведено теоретическое исследование кристаллической решетки диоксида титана (анатаза), его пространственных и термодинамических характеристик, особенностей роста граней и путей формирования его макромолекулярных структур. Показано, что термодинамически более благоприятным является рост вдоль направления с кристалла. Предложены варианты управления ростом тех или иных граней путем введения кислотных и основных компонентов, а также посредством изменения температуры.

Ключевые слова


диоксид титана; анатаз; наноструктура; термодинамические расчеты; кинетические особенности
