Title: Identifying low-coverage surface species on supported noble metal nanoparticle catalysts by DNP-NMR

Abstract

DNP-NMR spectroscopy has been applied to enhance the signal for organic molecules adsorbed on γ-Al₂O₃-supported Pd nanoparticles. In addition, by offering >2500-fold time savings, the technique enabled the observation of ¹³C-¹³C cross-peaks for low coverage species, which were assigned to products from oxidative degradation of methionine adsorbed on the nanoparticle surface.

Characterizing substrate–surface interactions on alumina-supported metal catalysts by dynamic nuclear polarization-enhanced double-resonance NMR spectroscopy [Characterizing substrate-surface interactions on alumina supported metal catalysts by DNP-enhanced double-resonance NMR spectroscopy]

Journal Article Perras, Frederic A. ; Padmos, J. Daniel ; Johnson, Robert L. ; ... - Journal of the American Chemical Society

The characterization of nanometer-scale interactions between carbon-containing substrates and alumina surfaces is of paramount importance to industrial and academic catalysis applications, but it is also very challenging. Here, we demonstrate that dynamic nuclear polarization surface-enhanced NMR spectroscopy (DNP SENS) allows the unambiguous description of the coordination geometries and conformations of the substrates at the alumina surface through high-resolution measurements of ¹³C–²⁷Al distances. We apply this new technique to elucidate the molecular-level geometry of ¹³C-enriched methionine and natural abundance poly(vinyl alcohol) adsorbed on γ-Al₂O₃-supported Pd catalysts, and we support these results with element-specific X-ray absorption near-edge measurements. Furthermore, this work clearlymore »« less

Probing the Surface Structure of Semiconductor Nanoparticles by DNP SENS with Dielectric Support Materials

Journal Article Hanrahan, Michael P. ; Chen, Yunhua ; Blome-Fernández, Rafael ; ... - Journal of the American Chemical Society

Surface characterization is crucial for understanding how the atomic-level structure affects the chemical and photophysical properties of semiconducting nanoparticles (NPs). Solid-state nuclear magnetic resonance spectroscopy (NMR) is potentially a powerful technique for the characterization of the surface of NPs, but it is hindered by poor sensitivity. Dynamic nuclear polarization surface enhanced NMR spectroscopy (DNP SENS) has previously been demonstrated to enhance the sensitivity of surface-selective solid-state NMR experiments by one to two orders of magnitude. Established sample preparations for DNP SENS experiments on NPs require the dilution of the NPs on mesoporous silica. Using hexagonal boron nitride (h-BN) to dispersemore »« less

Revealing the Configuration and Conformation of Surface Organometallic Catalysts with DNP-Enhanced NMR

Journal Article Perras, Frédéric A. ; Paterson, Alexander L. ; Syed, Zoha H. ; ... - Journal of Physical Chemistry. C

Although single-site, supported organometallic catalysts were designed with homogeneity in mind, little is strictly known about their atomic-level structure and uniformity. This is in large part due to the inability of conventional characterization tools to provide structural information with adequate resolution and range for this purpose. In this work, we show that dynamic nuclear polarization (DNP)-enhanced solid-state nuclear magnetic resonance (NMR) enables the measurement of distances between the surface and individual carbons, making it possible to orient complexes and molecules on surfaces. We use this approach to determine the orientation and configuration of naturally ¹³C-abundant acetate and supported organoiridium(III) pincermore »« less

Spatial distribution of organic functional groups supported on mesoporous silica nanoparticles: A study by conventional and DNP-enhanced ²⁹Si solid-state NMR

Journal Article Kobayashi, Takeshi ; Singappuli-Arachchige, Dilini ; Wang, Zhuoran ; ... - Physical Chemistry Chemical Physics. PCCP

Solid-state NMR spectroscopy, both conventional and dynamic nuclear polarization (DNP)-enhanced, was employed to study the spatial distribution of organic functional groups attached to the surface of mesoporous silica nanoparticles via co-condensation and grafting. The most revealing information was provided by DNP-enhanced two-dimensional ²⁹Si–²⁹Si correlation measurements, which unambiguously showed that post-synthesis grafting leads to a more homogeneous dispersion of propyl and mercaptopropyl functionalities than co-condensation. Furthermore, during the anhydrous grafting process, the organosilane precursors do not self-condense and are unlikely to bond to the silica surface in close proximity (less than 4 Å) due to the limited availability of suitably arrangedmore » hydroxyl groups.« less

A solid-state NMR investigation of the structure of mesoporous silica nanoparticle supported rhodium catalysts

Journal Article Rapp, Jennifer ; Huang, Yulin ; Natella, Michael ; ... - Solid State Magnetic Resonance

A detailed study of the chemical structure of mesoporous silica catalysts containing rhodium ligands and nanoparticles (RhP-MSN) was carried out by multi-dimensional solid-state NMR techniques. The degree of functionalization of the rhodium-phosphinosilyl complex to the surface of the RhP-MSN channels was determined by {sup 29}Si NMR experiments. The structural assignments of the rhodium-phosphinosilyl complex were unambiguously determined by employing the novel, indirectly detected heteronuclear correlation ({sup 13}C-{sup 1}H and {sup 31}P-{sup 1}H idHETCOR) techniques, which indicated that oxidation of the attached phosphinosilyl groups and detachment of Rh was enhanced upon syngas conversion.
