摘要：

The conversion of methane, the selectivity to C2 hydrocarbons, and, particularly, the ethene-to-ethane ratio are much higher over BiOCl-Li2CO3-MgO than those over pure BiOCl and BiOCl-MgO. In addition, they remain almost the same over a period of 5 h for the former system, but decline significantly for the other two systems (BiOCl and 10% BiOCl-MgO). The XPS investigations provide some insight about the processes responsible for this behavior, indicating that not only Cl but also Bi is likely to play a role.
