This work reports the synthesis of 80%Fe–10%Mo/10% Al2O3 catalysts via solution combustion synthesis using oxalic acid as fuel. The catalysts were tested in methane decomposition at 850 °C and 1 atm for 6 h. The synthesized samples were characterized by X-ray diffraction, transmission electron microscopy, photosedimentation analysis, etc. The specific carbon yield ranged from 5.8 to 8.4 g/gcat and the hydrogen yield from 1.0 to 1.4 mol/gcat, respectively. Catalytic decomposition of methane over Fe–Mo/Al2O3 led to the formation of mixture of bamboo-like carbon nanotubes and multi-walled carbon nanotubes. It was found that the highest yield of MWCNTs was reached at fuel-to-oxidizer ratio of 0.022.

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.
