DOI: 10.1021/acs.chemmater.7b00913
Abstract: Hierarchical ZSM-5 zeolite is hydrothermally synthesized in a single step with cetyltrimethylammonium (CTA) hydroxide acting as mesoporogen and structure-directing agent. Essential to this synthesis is the replacement of NaOH with KOH. An in-depth solid-state NMR… read more here.

DOI: 10.1039/d2cc04958a
Abstract: A surprising inversion of chirality of the -ITV zeolite framework is observed when the ethyl group of the enantiopure N,N-ethyl-methyl-pseudoephedrinium organic structure-directing agent is replaced by a benzyl or 2-methylbenzyl group, keeping the same molecular… read more here.

DOI: 10.1126/science.abg3793
Abstract: Description Zeolitic nanotubes Nanotubes generally have solid walls, but a low-dimensional version of zeolites now introduces porosity into such structures. Korde et al. used a structure-directing agent with a hydrophobic biphenyl group center connecting two… read more here.
