Ethanol decomposition to co-produce multi-walled carbon nanotubes and hydrogen-rich gas at temperatures of 600-800 ℃ was inves- tigated over the synthesized Ni-Mo/MgO catalysts. The results showed that the catalytic activity depended strongly on the reaction temperature and loading ratio of Ni ： Mo. According to the gaseous and solid products obtained, the reaction pathways for ethanol decomposition were suggested.展开更多
