Fe-Mo/Al₂O₃ катализатор разложения метана, синтезированный методом горения раствора с использованием щавелевой кислоты

В данной работе сообщается о синтезе катализаторов 80%Fe-10%Mo/10%Al₂O₃ методом растворного горения с использованием щавелевой кислоты в качестве топлива. Катализаторы были испытаны в реакции разложения метана при 850 °C и 1 атм в течение 6 ч. Синтезированные образцы были охарактеризованы методами рентгеновской дифракции, просвечивающей электронной микроскопии, фотоседиментационного анализа и др. Удельный выход углерода составил от 5,8 до 8,4 г/гкат, а выход водорода - от 1,0 до 1,4 моль/гкат соответственно. Каталитическое разложение метана на Fe-Mo/Al₂O₃ приводило к образованию смеси бамбукоподобных и многостенных углеродных нанотрубок. Было установлено, что наивысший выход МУНТ достигался при соотношении топливо/окислитель, равном 0,022.
