The Cover Feature shows an artist impression of the electrocatalytic reduction of CO₂ by bispyridine-bearing Fe porphyrin hangman complexes. In their Full Paper, A. R. Ramuglia et al. describe how this structural design achieves to permanently position metal cations in close vicinity to the Fe active site and thus allows for stabilisation of reaction intermediates, such as the high energy carboxylate intermediate, and hence accelerate the overall catalytic reaction. More information can be found in the Full Paper by A. R. Ramuglia et al.

封面特征：具有侧链吡啶取代基的铁卟啉复合物通过第二配位球效应促进电催化 CO2 还原 (ChemCatChem 18/2021)

Cover Feature展示了通过含双吡啶的 Fe 卟啉刽子手复合物电催化还原 CO ₂的艺术印象。在他们的全文中，A. R. Ramuglia 等人。描述这种结构设计如何实现将金属阳离子永久定位在 Fe 活性位点附近，从而稳定反应中间体，例如高能羧酸盐中间体，从而加速整个催化反应。更多信息可以在 A. R. Ramuglia 等人的全文中找到。
