The Cover Feature shows how methane from natural gas can be upgraded directly into benzene and hydrogen, both of which are chemical commodities, through the catalytic methane aromatization reaction using mixed Mo‐C‐Fe species supported on a ZSM‐5 structure. In their Full Paper, A. Sridhar et al. demonstrate that adding small quantities of Fe oxide to Mo oxide supported on ZSM‐5 enhances the yield to benzene, because iron modifies the nature of the active sites. The amount of added Fe affects both the quantity and morphology of the carbon deposits explaining the differences in catalytic stability. Additionally, both benzene yield and catalytic stability are enhanced by precarburization of the catalysts to form modified Mo carbide species before reaction. More information can be found in the Full Paper by A. Sridhar et al. on page 2571 in Issue 12, 2018 (DOI: 10.1002/cctc.201800002).
