The Cover Feature shows a highly porous cellulose‐based nanosponge (CNS) used as a recoverable catalyst for Henry and Knoevenagel reactions. This material is obtained by cross‐linking TEMPO‐oxidized cellulose nanofibers (TOCNF) and branched polyethyleneimine 25 kDa (bPEI) in the presence of citric acid. In their Full Paper, L. Riva et al. describe a micro‐ and nano‐porous system that ensures a complete penetration of the reagents within the CNS, guaranteeing high conversions and remarkable selectivity by modulating the reaction conditions. The catalyst could be also re‐used several times without losing its catalytic efficiency. More information can be found in the Full Paper by L. Riva et al.

封面文章：纤维素生物质的共聚纳米海绵作为胺催化的有机反应的多相催化剂（ChemCatChem 24/2020）

Cover Feature展示了一种高度多孔的纤维素纳米海绵（CNS），可用作Henry和Knoevenagel反应的可回收催化剂。这种材料是通过在柠檬酸存在下使TEMPO氧化的纤维素纳米纤维（TOCNF）与25 kDa的支链聚乙烯亚胺（bPEI）交联而获得的。L. Riva等人在其论文全文中。描述了一种微孔和纳米孔系统，该系统可确保试剂在CNS内完全渗透，并通过调节反应条件来确保高转化率和出色的选择性。催化剂也可以重复使用几次，而不会损失其催化效率。可以在L. Riva等人的论文全文中找到更多信息。
