Title: Morphology of Palladium Thin Film Deposited on a Two-Dimensional Bilayer Aluminosilicate

Abstract

The morphology of a thin palladium film deposited on bilayer Al_0.35Si_0.65O₂/Ru(0001), previously proposed as a two-dimensional zeolite model, is investigated using a set of complementary spectroscopy and microscopy tools. Pd single atoms are known to penetrate the bilayer silica, but when a thick Pd film is deposited on the aluminosilicate case some of the metal remains on top of the bilayer oxide. Annealing this surface results in a decrease in the Pd/Si ratio seen in X-ray photoelectron spectroscopy, indicating either further permeation of Pd, or dewetting of surface Pd to form nanoparticles and leave aluminosilicate exposed. An interesting observation is that two very distinct morphologies are obtained for the film. On small narrow terraces, flat wetting films are produced, while on larger terraces Pd particles leaving a partially exposed bilayer aluminosilicate framework are obtained.

First-Principles Study of Interface Structures and Charge Rearrangement at the Aluminosilicate/Ru(0001) Heterojunction

Journal Article Wang, Mengen ; Zhong, Jian-Qiang ; Stacchiola, Dario J. ; ... - Journal of Physical Chemistry. C

Aluminosilicate bilayer films consisting of corner-sharing [SiO₄] and [AlO₄] tetrahedra on a metal substrate are important model systems to study zeolite chemistry in heterogeneous catalysis. Understanding the interfacial electronic properties of the aluminosilicate/metal heterojunction is a fundamental step to rationalize the structure–property–function relationship essential to the catalytic activities of the model zeolite. In this work, we use density functional theory (DFT) to investigate the charge rearrangement at the aluminosilicate/Ru(0001) interface, which is attributed to hybridizations between the O p_z and Ru d_z2 and s orbitals and the subsequent electron redistribution. We found that the energy level alignment at the aluminosilicate/Ru(0001)more »« less

First-Principles Study of n-Butane Monomolecular Cracking and Dehydrogenation on Two-Dimensional-Zeolite Model Systems: Reaction Mechanisms and Effects of Spatial Confinement

Journal Article Wang, Mengen ; Boscoboinik, Jorge Anibal ; Lu, Deyu - Journal of Physical Chemistry. C

Two-dimensional (2D) ultrathin (~0.5 nm) aluminosilicate bilayer films, consisting of hexagonal prisms (a.k.a. double 6-membered rings D6R) with acidic bridging hydroxyl groups exposed on the surface, have been previously synthesized on a Ru(0001) surface as a zeolite model system. These structures are helpful for mimicking zeolite catalysts with D6R building blocks, such as chabazite. We performed density functional theory calculations to investigate the monomolecular cracking and dehydrogenation of n-butane molecules over the acidic hydroxyl groups of the 2D model system and compared the reaction energetics with that in bulk chabazite. The intrinsic activation energy barrier is the highest for dehydrogenationmore »« less

Energy level shifts at the silica/Ru(0001) heterojunction driven by surface and interface dipoles

Journal Article Wang, Mengen ; Zhong, Jian -Qiang ; Kestell, John ; ... - Topics in Catalysis

Charge redistribution at heterogeneous interfaces is a fundamental aspect of surface chemistry. Manipulating the amount of charges and the magnitude of dipole moments at the interface in a controlled way has attracted tremendous attention for its potential to modify the activity of heterogeneous catalysts in catalyst design. Two-dimensional ultrathin silica films with well-defined atomic structures have been recently synthesized and proposed as model systems for heterogeneous catalysts studies. R. Wlodarczyk et al. (Phys. Rev. B, 85, 085403 (2012)) have demonstrated that the electronic structure of silica/Ru(0001) can be reversibly tuned by changing the amount of interfacial chemisorbed oxygen.

Growth and characterization of Rh and Pd nanoparticles on oxidized and reduced CeOx(111) thin films by STM

Journal Article Zhou, Jing ; Baddorf, Arthur P ; Mullins, David R ; ... - Journal of Physical Chemistry C

The growth and structure of Rh and Pd nanoparticles on vapor-deposited ceria thin films grown epitaxially on Ru(0001) were investigated by scanning tunneling microscopy as a function of coverage, postdeposition annealing temperatures, as well as ceria oxidation states. Both metals grow as three-dimensional nanoparticles on the fully oxidized CeO{sub 2}(111) thin films at room temperature. At low coverage, Rh particles preferentially decorate step edges on ceria, forming particles with smaller average size than those on the terraces. With increasing coverage, the number of Rh particles increases until near 2.3 monolayers, where the Rh particles cover most of the ceria surfacemore »« less
