The Front Cover shows the Fisher‐Tropsch synthesis that is industrially used for converting carbon‐containing feedstocks, such as coal, natural gas, biomass, and municipal waste, via the production of synthesis gas (a mixture of CO + H2), into hydrocarbons. In their Review, P. P. Paalanen and B. M. Weckhuysen focus on Fe‐based Fischer‐Tropsch catalysis, emphasizing the process conditions and catalyst compositions available for steering the various carbon pathways from input CO and their associated reactions. Special attention is paid to the role of chemical promotion of alkali, namely Na and K, as well as sulfur (S). The cover image illustrates this with a dashboard panel. Methane selectivity, chain growth probability (α) and CO conversion can be tuned by varying the amounts of Na, K and S in the catalyst material. More information can be found in the Review, P. P. by Paalanen and B. M. Weckhuysen.
