TL;DR: It is shown that appropriately designed bifunctional surfactants can direct the formation of zeolite structures on the mesoporous and microporous length scales simultaneously and thus yield MFI (ZSM-5, one of the most important catalysts in the petrochemical industry) zeolites that are only 2 nm thick, which corresponds to the b-axis dimension of a single MFI unit cell.

TL;DR: The synthesis of the crystalline aluminosilicate materials with tunable mesoporosity and strong acidity has potentially important technological implications for catalytic reactions of large molecules, whereas conventional mesoporous materials lack hydrothermal stability and acidity.

TL;DR: It is reported that a sulfur-doped zeolite-templated carbon, simultaneously exhibiting large sulfur content, as well as a unique carbon structure (that is, highly curved three-dimensional networks of graphene nanoribbons), can stabilize a relatively high loading of platinum in the form of highly dispersed species including site isolated atoms.

TL;DR: In this paper, the effects of mesoporosity on catalyst longevity of methanol-to-hydrocarbon (MTH) reactions have been investigated using a number of MFI zeolites with different degrees of mesophorosity, which were obtained via the post-synthetic desilication, dry-gel conversion in nanocarbon templates, and hydrothermal synthesis with the addition of organosilane surfactants.

TL;DR: In this article, an image of the porous structure of SBA-15 and low-pressure argon adsorption was used to draw a coherent picture of the evolution of the precursor mesophase as a function of the synthesis temperature.
