Title: Polar surface structure of oxide nanocrystals revealed with solid-state NMR spectroscopy

Abstract

Compared to nanomaterials exposing nonpolar facets, polar-faceted nanocrystals often exhibit unexpected and interesting properties. The electrostatic instability arising from the intrinsic dipole moments of polar facets, however, leads to different surface configurations in many cases, making it challenging to extract detailed structural information and develop structure-property relations. The widely used electron microscopy techniques are limited because the volumes sampled may not be representative, and they provide little chemical bonding information with low contrast of light elements. With ceria nanocubes exposing (100) facets as an example, here we show that the polar surface structure of oxide nanocrystals can be investigated by applying ¹⁷O and ¹H solid-state NMR spectroscopy and dynamic nuclear polarization, combined with DFT calculations. Both CeO₄-termination reconstructions and hydroxyls are present for surface polarity compensation and their concentrations can be quantified. These results open up new possibilities for investigating the structure and properties of oxide nanostructures with polar facets.

Fast MAS ¹H NMR Study of Water Adsorption and Dissociation on the (100) Surface of Ceria Nanocubes: A Fully Hydroxylated, Hydrophobic Ceria Surface

Journal Article Gill, Lance ; Beste, Ariana ; Chen, Banghao ; ... - Journal of Physical Chemistry. C

¹H nuclear magnetic resonance (NMR) spectroscopy was used to study hydroxylic surface species on ceria nanocubes, a crystalline, high-surface-area CeO₂ that presents mostly (100) facets. Water adsorption and desorption experiments in combination with fast magic angle spinning (MAS, 20–40 kHz) 1H NMR provide high-resolution ¹H spectra that allow the observation of ten resonance bands (water or hydroxyl) on or under the (100) surface. Assignments were made using a combination of adsorption and temperature-programmed desorption, quantitative spin counting, deuterium exchange, spin–lattice (T₁) and spin–spin (T₂) relaxation, and DFT calculations. In air, the (100) surface exists as a fully hydroxylated surface. Watermore »« less

Surface Structure Dependence of SO₂ Interaction with Ceria Nanocrystals with Well-defined Surface Facets

Journal Article Tumuluri, Uma ; Li, Meijun ; Cook, Brandon G. ; ... - Journal of Physical Chemistry. C

The effects of the surface structure of ceria (CeO₂) on the nature, strength, and amount of species resulting from SO₂ adsorption were studied using in situ IR and Raman spectroscopies coupled with mass spectrometry, along with first-principles calculations based on density functional theory (DFT). CeO₂ nanocrystals with different morphologies, namely, rods (representing a defective structure), cubes (100 facet), and octahedra (111 facet), were used to represent different CeO₂ surface structures. IR and Raman spectroscopic studies showed that the structure and binding strength of adsorbed species from SO₂ depend on the shape of the CeO₂ nanocrystals. SO₂ adsorbs mainly as surfacemore »« less

Surface-structure sensitivity of CeO₂ nanocrystals in photocatalysis and enhancing the reactivity with nanogold

Journal Article Lei, Wanying ; Zhang, Tingting ; Gu, Lin ; ... - ACS Catalysis

Structure–function correlations are a central theme in heterogeneous (photo)catalysis. In this research, using aberration-corrected scanning transmission electron microscopy (STEM), the atomic surface structures of well-defined one-dimensional (1D) CeO₂ nanorods (NRs) and 3D nanocubes (NCs) are directly visualized at subangstrom resolution. CeO₂ NCs predominantly expose the {100} facet, with {110} and {111} as minor cutoff facets at the respective edges and corners. Notably, the outermost surface layer of the {100} facet is nearly O-terminated. Neither surface relaxations nor reconstructions on {100} are observed, indicating unusual polarity compensation, which is primarily mediated by near-surface oxygen vacancies. The surface of CeO₂ NRs ismore »« less

Revealing the Structure and Oxygen Transport at Interfaces in Complex Oxide Heterostructures via ¹⁷ O NMR Spectroscopy

Journal Article Hope, Michael A. ; Zhang, Bowen ; Zhu, Bonan ; ... - Chemistry of Materials

Vertically aligned nanocomposite (VAN) films, comprising nanopillars of one phase embedded in a matrix of another, have shown great promise for a range of applications due to their high interfacial areas oriented perpendicular to the substrate. In particular, oxide VANs show enhanced oxide-ion conductivity in directions that are orthogonal to those found in more conventional thin-film heterostructures; however, the structure of the interfaces and its influence on conductivity remain unclear. In this work, ¹⁷O NMR spectroscopy is used to study CeO₂–SrTiO₃ VAN thin films: selective isotopic enrichment is combined with a liftoff technique to remove the substrate, facilitating detection ofmore »« less

Characterization of Silicon Nanocrystal Surfaces by Multidimensional Solid-State NMR Spectroscopy

Journal Article Hanrahan, Michael P. ; Fought, Ellie L. ; Windus, Theresa L. ; ... - Chemistry of Materials

The chemical and photophysical properties of silicon nanocrystals (Si NCs) are strongly dependent on the chemical composition and structure of their surfaces. Here we use fast magic angle spinning (MAS) and proton detection to enable the rapid acquisition of dipolar and scalar 2D 1H-29Si heteronuclear correlation (HETCOR) solid-state NMR spectra and reveal a molecular picture of hydride-terminated and alkyl-functionalized surfaces of Si NCs produced in a nonthermal plasma. 2D 1H-29Si HETCOR and dipolar 2D 1H-1H multiple-quantum correlation spectra illustrate that resonances from surface mono-, di-, and trihydride groups cannot be resolved, contrary to previous literature assignments. Instead the 2D NMRmore »« less
