The Cover Feature shows a high‐speed train, representing non‐oxidative propane dehydrogenation, running on a monorail connected to specific atoms (active sites) on a catalyst surface. In their Full Paper, S. Büchele et al. elucidate the role of distinct nitrogen and oxygen groups (colored spheres) in carbon‐based catalysts and their stability under reaction conditions. While several species potentially catalyze the reaction, carbonyl groups (red spheres) comprise the dominant active site. Catalyst deactivation occurs through propane‐driven oxygen loss and can be alleviated by post‐treatment of the carbon with KOH to boost oxygen content and surface area. More information can be found in the Full Paper by S. Büchele et al.
