Ultrasmall palladium nanoparticles (1.5–2.5 nm) encapsulated within the highly porous and hydrothermally stable amine-functionalized metal–organic framework UiO-66 exhibit excellent catalytic activity for the selective conversion of vanillin to 2-methoxy-4-methylphenol.

Li 2 ZrO 3 nanocrystals with improved CO 2 capture properties were synthesized by a citrate sol-gel method. The morphology and structure of the synthesized Li 2 ZrO 3 samples were characterized in detail by SEM, TEM, and XRD techniques. The CO 2 capture-regeneration properties of these nanocrystals were investigated by thermogravimetric analysis (TGA) over a wide range of temperatures and of CO 2 partial pressures. The nanosized Li 2 ZrO 3 crystallites with a tetragonal phase exhibit a better CO 2 capture performance than reported sorbents, exhibiting a faster uptake and a higher, nearly stoichiometric adsorption capacity (26 wt.%). Furthermore, the adsorbent shows a good stability, confirmed by capture-regeneration cycles. Based on these excellent properties, application in sorptionenhanced reaction process (SERP) is anticipated.

Two-dimensional zeolite nanosheets that do not contain any organic structure-directing agents were prepared from a multilamellar MFI (ML-MFI) zeolite. ML-MFI was first exfoliated by melt compounding and then detemplated by treatment with a mixture of H2 SO4 and H2 O2 (piranha solution). The obtained OSDA-free MFI nanosheets disperse well in water and can be used for coating applications. Deposits made on porous polybenzimidazole (PBI) supports by simple filtration of these suspensions exhibit an n-butane/isobutane selectivity of 5.4, with an n-butane permeance of 3.5×10(-7)  mol m(-2)  s(-1)  Pa(-1) (ca. 1000 GPU).
