2-Methylimidazolate linkers of Pt@ZIF-8
are exchanged with imidazolate using solvent-assisted linker exchange
(SALE) to expand the apertures of the parent material and create Pt@SALEM-2.
Characterization of the material before and after SALE was performed.
Both materials are active as catalysts for the hydrogenation of 1-octene,
whereas the hydrogenation of <i>cis</i>-cyclohexene occurred
only with Pt@SALEM-2, consistent with larger apertures for the daughter
material. The largest substrate, β-pinene, proved to be unreactive
with H<sub>2</sub> when either material was employed as a candidate
catalyst, supporting the contention that substrate molecules, for
both composites, must traverse the metal–organic framework
component in order to reach the catalytic nanoparticles
