AbstractThe behavior of different species during the temperature-programmed surface reaction (TPSR) of methane over various catalysts is traced by an on-line mass spectrometer. It is demonstrated that the transformation of MoO3 to molybdenum carbide hinders the activation of methane as well as the succeeding aromatization in the TPSR. If this transformation process is done before the reaction, the temperature needed for methane activation and benzene formation will be greatly lowered (760 K and 847 K, respectively). It is strongly suggested that molybdenum carbide is one of the active center of this catalytic process.
