Золь-гель методом в сочетании с термохимической конденсацией осуществлен синтез композитов на основе феррита магния и нитрида углерода. Влияние способа синтеза на кристаллическую структуру, фазовый и химический состав, морфологию композитов изучено методами дифракции рентгеновских лучей, ИК-спектроскопии, сканирующей электронной микроскопии и энергодисперсионной рентгеновской спектроскопии. Установлено, что в зависимости от последовательности проведения стадий золь-гель перехода, инициирования самораспространяющегося высокотемпературного синтеза и термохимической конденсации меламина образуются композиты с различной кристаллической структурой и морфологией. Полученные результаты имеют важное значение при разработке гетерогенных Фентон- и фото-Фентон катализаторов на основе композитов феррита магния и нитрида углерода.

The composites based on magnesium ferrite and carbon nitride were synthesized by the sol-gel method in combination with thermochemical condensation. The effect of the synthesis method on the crystalline structure, the phase and chemical composition, and the morphology of composites was studied by the X-ray diffraction, IR spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy techniques. It was found that, depending on the conditions of the sol-gel stages, the initiation of self-combustion high-temperature synthesis and melanin thermochemical condensation, composites with different crystalline structure and morphology were prepared. The obtained results are important for the development of the heterogeneous Fenton- and photo-Fenton catalysts based on magnesium ferrite and carbon nitride composites.
