| 제목 | Aromatization of methane and other hydrocarbons over Mo2C catalysts |
| 초록 | The upgrading of lower alkanes is an important subject of heterogeneous catalysis. Early studies focussed mainly on Pt catalysts, which exhibited an outstanding catalytic performance among the metals. All these studies were exclusively restricted to the reactions of C2-C7 hydrocarbons. The discovery of Wang et al.[1] that methane can be converted into benzene on MoO3/ZSM-5 opened a new route for the utilization of methane. It turned out, however, that not the MoO3 but Mo2C is the key component for the activation and aromatization of methane, which is formed from MoO3 during the induction period of the reaction. Methane can be converted into benzene on Mo2C/ZSM-5 with ~80% selectivity at a conversion of ~15% at 973 K. In our laboratory, we have worked in two directions: (i) elaborating the effect of Mo2C on the aromatization of C1-C7 hydrocarbons, and (ii) studying the chemistry of hydrocarbon species (CH2, CH3, C2H5, C3H5, C4H9 and C5H11), the primary products of the activation of the above compounds, on Mo2C/Mo(100) in UHV by several spectroscopic methods.
