Synthesis, characterization and isomerization performance of micro/mesoporous materials based on H-ZSM-22 zeolite
TL;DR: In this paper, micro/mesoporous materials with different mesoporosities were prepared through recrystallization of H-ZSM-22 zeolite in alkaline solution with cetyltrimethylammonium bromide template (CTAB).
Journal ArticleDOI
Synthesis and characterization of the Fe-substituted ZSM-22 zeolite catalyst with high n-dodecane isomerization performance
TL;DR: In this paper, Fe substitution for Al in ZSM-22 zeolite framework especially reduces the B acidity and exhibits improved isomerization performance, and characterizations confirm the Fe incorporation in the ZSM22 framework.

Hierarchical zeolites: enhanced utilisation of microporous crystals in catalysis by advances in materials design.
Javier Pérez-Ramírez,Claus H. Christensen,Kresten Egeblad,Christina Hviid Christensen,Johan C. Groen +4 more
TL;DR: This critical review examines recent advances in the rapidly evolving area of zeolite with improved accessibility and molecular transport and particularly dwells on the exciting field of hierarchical zeolites, which couple in a single material the catalytic power of micropores and the facilitated access and improved transport consequence of a complementary mesopore network.

Synthesis of self-pillared zeolite nanosheets by repetitive branching.
Xueyi Zhang,Dongxia Liu,Dandan Xu,Shunsuke Asahina,Katie A. Cychosz,Kumar Varoon Agrawal,Yasser Al Wahedi,Aditya Bhan,Saleh Al Hashimi,Osamu Terasaki,Osamu Terasaki,Matthias Thommes,Michael Tsapatsis +12 more
TL;DR: Zhang et al. (p. 1684) show that a hierarchical zeolite can be made through a simple process using a single structure-directing agent that causes repetitive branching, which leads to a material with improved transport and catalytic properties.
Journal ArticleDOI
Design of hierarchical zeolite catalysts by desilication
TL;DR: Hierarchical (or mesoporous) zeolites have received an everincreasing attention due to their improved performance in catalysed reactions with respect to conventional (purely microporous) Zeolites as discussed by the authors.
