The Front Cover shows a supported Fe5C2 catalyst, which was designed and prepared with mesoporous carbon as the carrier. The oxygen‐containing functional groups (especially COOH group) on the surface of the carbon inhibit the formation of iron carbides. However, the mesoporous carbon exhibits a positive effect on the dispersion of iron species. In their Research Article, Y. Zhao and co‐workers suggest a practical strategy in fabricating a supported iron carbides catalyst for the chemosynthesis of ethanol via DMO hydrogenation from syngas. More information can be found in the Research Article by M. Cao, H. Huang et al.

Due to the low activity of bulk Fe 5 C 2 catalyst in the hydrogenation of dimethyl oxalate to ethanol, a supported Fe 5 C 2 catalyst was designed and prepared with mesoporous carbon as the carrier. For a comparison, two iron carbide catalysts supported on activated carbon and microporous carbon were also prepared. Based on the characterization results of IR, XRD, H 2 -TPR, CO-TPD, XPS and MES, the oxygen-containing functional groups (especially COOH group) on the surface of the carbon supports inhibit the formation of iron carbides, which are regarded as the active sites and play the key role in the hydrogenation of dimethyl oxalate to ethanol. However, the mesoporous carbon exhibits a more positive effect on the dispersion of iron particles than the other two carbon supports. As a result, the as-prepared mesoporous catalyst presents an excellent activity (the ethanol yield of 85.8 %) and stability in the hydrogenation of dimethyl oxalate. This work suggests a practical strategy in fabricating a supported iron carbides catalyst for the chemosynthesis of ethanol via DMO hydrogenation from syngas.
