Chemical Environment Control and Enhanced Catalytic Performance of Platinum Nanoparticles Embedded in Nanocrystalline Metal-Organic Frameworks.
TL;DR: It is found that organic linkers with two functional groups, sulfonic acid and ammonium, play a critical role in product selectivity and activity in the gas-phase conversion of methylcyclopentane to acyclic isomer, olefins, cyclohexane, and benzene.

TL;DR: Rare examples of nMOFs grown in monocrystalline form around metal NCs are shown and these constructs are found to be active in gas-phase hydrogenative conversion of methylcyclopentane (MCP) and give unusual product selectivity.
MFI Titanosilicate Nanosheets with Single-Unit-Cell Thickness as an Oxidation Catalyst Using Peroxides
TL;DR: Titanosilicate MFI (a three-letter structural code among ∼200 zeolite framework codes) nanosheets of single-unit-cell thickness were synthesized with a diquaternary ammonium surfactant as the Zeolite structure-directing agent.

TL;DR: In this paper, the two-level structure-directing effects have been investigated for various molecules with the formula of tail-N+(CH3)2-{spacer-N+R2}n−1-R*. Here, n is varied over 1−4.

Disordered Assembly of MFI Zeolite Nanosheets with a Large Volume of Intersheet Mesopores
TL;DR: MFI zeolite nanosheets with a single unit-cell crystal thickness were syn-thesized under hydrothermal synthesis conditions using diquaternary ammonium surfactants as the Zeolite structure-generatin this article.
