Mesoporous MFI Zeolite Nanosponge Supporting Cobalt Nanoparticles as a Fischer–Tropsch Catalyst with High Yield of Branched Hydrocarbons in the Gasoline Range
TL;DR: In this paper, a zeolite nanosponge was obtained by a seed-assisted hydrothermal synthesis route using C22H45−N+(CH3)2−C6H12−N+CH3−N−C 6H13 as the structure-directing agent.

TL;DR: The selectivity was revealed to be Pt size-dependent, with improved isomer production as Pt sizes increased from 1.7 to 5.5 nm, and the selectivity toward branched C6 isomers was further increased.

TL;DR: Several types of mesoporous aluminosilicates were synthesized and evaluated in the catalytic isomerization of n-hexane, both with and without Pt nanoparticles loaded into the mesopores, and found that the strong Brönsted acid sites in the micropores of the zeolite catalysts facilitated the cracking of hexane.
Cyclic diquaternary ammoniums for nanocrystalline BEA, MTW and MFI zeolites with intercrystalline mesoporosity
TL;DR: In this article, phase diagrams for these nanocrystalline zeolites have been constructed using sodium silicate as a silica source, and their morphologies and intercrystalline mesoporosity have been characterized by electron microscopy and N2 adsorption.

Colloidal Metal Nanocatalysts: Synthesis, Characterization, and Catalytic Applications
TL;DR: In this article, the authors highlight the recent progress on general colloidal synthetic routes with technological advances in characterization tools that enable the atomic-scale observation of metal nanoparticles and discuss their structure-dependent contributions on the control of product selectivity and turnover rate.
