The Cover shows the transition of face centered cubic to hexagonal packed cobalt via the carbide intermediate on a catalyst support. Control of the cobalt structure is vital for Fischer–Tropsch chemistry, which is a highly significant reaction in industry for the gas to liquids fuels process.In their Full Paper, J. Paterson et al. demonstrate the transition to the more active hexagonal phase using in situ X‐ray diffraction and present the catalysis results supporting it. Moreover, the effect of CO is studied, showing the effect of partial pressures between 0 and 10 bar, the facile removal under hydrogen and the ability of CO to complete the full reduction of the cobalt oxide precursor. Future catalyst and process designs may benefit from these mechanistic insights, leading to improved performance, greater activity and enhanced selectivity. More information can be found in the Full Paper by J. Paterson et al. on page 3463 in Issue 18, 2017 (DOI: 10.1002/cctc.201700754).

封面文章：费-托催化剂的原位衍射：钴还原和碳化物形成（ChemCatChem 18/2017）

封面图1显示了通过催化剂载体上的碳化物中间体，面心立方晶向六方填充钴的过渡。钴结构的控制对于费托化学非常重要，费托化学在工业中对于气制液燃料过程是非常重要的反应。在其论文全文中，J。Paterson等人。演示了使用原位X射线衍射过渡到更具活性的六方相的过程，并提出了支持该相的催化结果。此外，还研究了CO的影响，显示了分压在0至10 bar之间的影响，在氢气下的轻松去除以及CO完成氧化钴前体的完全还原的能力。未来的催化剂和工艺设计可能会受益于这些机械的见解，从而提高性能，提高活性并提高选择性。可以在J. Paterson等人的《全文》中找到更多信息。上2017年第18期，第3463页（DOI：10.1002 / cctc.201700754）。
