The development of industrial catalysts is of crucial importance for practical uses. However, the use of extruded catalysts in industry is still limited because of a remarkably decreased catalytic activity when combining them with binders. This contribution illustrates the rational design of binder-free hierarchical ZSM-5 pellets and monoliths derived from zeolite@LDHs composites via extrusion and 3D printing technologies, respectively. The designed catalyst applied in bioethanol dehydration boosts the ethylene yield by over 93.4 ± 2.2% due to the synergistic effect of zeolites and LDHs.

由 ZSM-5@LDHs 复合材料衍生的无粘合剂分级沸石颗粒和整体式用于生物乙醇脱水制乙烯
工业催化剂的开发对于实际应用至关重要。然而，挤出催化剂在工业中的使用仍然受到限制，因为当它们与粘合剂结合时催化活性显着降低。这一贡献说明了通过挤出和 3D 打印技术分别从 zeolite@LDHs 复合材料衍生的无粘合剂分层 ZSM-5 颗粒和整体材料的合理设计。由于沸石和 LDH 的协同作用，设计的用于生物乙醇脱水的催化剂将乙烯收率提高了 93.4 ± 2.2% 以上。
