Herein, the effect of various treatments subjected to FAU zeolites to introduce mesoporosity has been examined on their efficiency as catalyst in the cyclisation of O-aryl 3-arylpropynoic acid ester to its corresponding coumarin.

The addition of bio-sourced lignin residues in the alkaline desilication treatment induced the generation of supplementary mesoporosity, thus offering an optimal micro- and mesopores combination with respect to targeted activity and selectivity.

The so-called bio-sourced secondary template (BSST) concept in the design of zeolite-based catalysts could be assessed. The use of renewable wood feedstocks can therefore be a valuable strategy for the zeolite post-modification, thus for the design of porous zeolite catalysts.

在此，已经研究了在FAU沸石上进行各种处理以引入介孔性的效果，作为它们在O-芳基3-芳基丙炔酸酯环化成其相应的香豆素中的催化剂的效率。

添加生物来源的木质素在诱导补充中孔隙的产生碱性脱硅处理残留物，从而提供最佳的微和中孔相对于目标的活性和选择性的组合。

可以评估沸石基催化剂设计中所谓的生物来源的二次模板（BSST）概念。因此，对于沸石的后改性，因此对于多孔沸石催化剂的设计，可再生木材原料的使用可能是有价值的策略。
