To understand steam reforming of methanol (SRM) reaction pathways over the surfaces of various metal-modified molybdenum carbides, the reaction intermediate species generated during the SRM reaction are investigated by using a temperature programmed surface reaction (TPSR) approach, in which a mass spectroscopy is applied to detect the produced species on-line. It is found that the reaction temperature affects the formation of different intermediate species over different catalysts. At the temperature lower than 180 °C, SRM reaction proceeds over Cu modified molybdenum carbide surface through formic acid (HCOOH) intermediate pathway, but at the temperature over 180 °C, the reactions over pure β-Mo2C, Ni, Cu and Pt modified molybdenum carbide surfaces proceed through methyl-formate (HCOOCH3) intermediate pathway. It is expected that these findings can help us to understand the mechanism on SRM reaction over molybdenum carbide based catalysts.
