The Front Cover shows a series of K and S promoted Fe‐based catalysts with different particle sizes for direct conversion of syngas to lower olefins. The volcanic curve observed for the catalytic performance as a function of particle size is evidence of the shape‐sensitivity of Fe‐based catalysts in Fischer‐Tropsch synthesis.In their Full Paper, Y. Yuan et al. propose a novel method to fabricate monodisperse nano‐Fe 3 O 4 on α‐Al 2 O 3 catalysts, in which nanomaterials preparation was merged into the design of the supported catalyst. Particle size showed a significant influence on CO conversion. Furthermore, a synergistic effect of K and S resulted in high activity with enhanced lower olefin selectivity.
