The Cover shows a representative idea of methane to syngas conversion. Energy/fuel related industrial catalysis occurs at high to very high temperatures. A fundamental understanding of them might lead to develop better catalysts to work under milder conditions. C−H activation is a perennial issue and a surprise was waiting to explore it on Mn‐doped Ce 1− x Zr x O 2 by molecular beam methods. In their Full Paper, A. Dubey et al. describe a key finding of competition and cooperation among the elementary reactions. Though CO, CO 2 and H 2 O formation are oxidation reactions, the former two occur under O 2 ‐less conditions. Diffusion of H‐atoms is so fast that it simply desorbs as H 2 under O 2 ‐less, and forms water under O 2 ‐rich conditions. A combination of fast oscillation between O 2 ‐rich and lean reaction mixtures with low contact time could lead to highly selective syngas at 700‐900 K. More information can be found in the Full Paper by A. Dubey et al. on page 2296 in Issue 13, 2016 (DOI: 10.1002/cctc.201600365).
