abstract = {Modified aluminum phosphate (APO-5) proved suitable as
zeotype support for the preparation of imidazolium-based
supported ionic liquid phase material, i.e. SILP(APO-5). The
successful chemisorption of ionic liquid-like modifiers at
the APO-5 surface was demonstrated by solid- state $^{31}$P
and $^{13}$C nuclear magnetic resonance (NMR) spectroscopy.
The immobilization of Ru nanoparticles (NPs) on SILP(APO-5)
was achieved following an organometallic approach, producing
well-dispersed Ru NPs with a mean average size of 1.4 nm on
the support. The resulting Ru@SILP(APO-5) material was
thoroughly characterized using multiple techniques, e.g.,
solid-state NMR, transmission electron microscopy (TEM),
infrared (IR) spectroscopy, X-ray absorption spectroscopy
(XAS), and applied as a catalyst for the hydrogenation of
biomass-derived furfural acetone with molecular hydrogen.
The ionic liquid-like layer was found beneficial for the
stabilization of the Ru NPs as well as of the APO-5
material. A temperature-controlled selectivity switch
between olefinic, carbonyl or furan ring hydrogenation could
be achieved with this new material with the APO-5
facilitating activation of the olefinic bond, while the
carbonyl bond was remarkably deactivated. The demonstrated
suitability of aluminum phosphate materials to produce
molecularly modified surfaces offers a new control parameter
for the systematic design and optimization of zeotype-based
catalysts.},
