Title: Visualizing the origin of rotational entropy effects in coadsorbed systems

Abstract

We demonstrate that significant entropic effects govern the stability of rotationally constrained molecular complexes on surfaces. Using a complementary combination of low-temperature scanning tunneling microscopy, temperature programmed desorption, and density functional theory calculations, we probe the energetics of surface adsorbed molecular rotors as well as their corresponding rotationally hindered complexes. The results reveal that absorbate-absorbate interactions can significantly decrease the rotational entropy associated with such complexes leading to lower than expected desorption temperatures.

Carbon Monoxide Mediated Hydrogen Release from PtCu Single-Atom Alloys: The Punctured Molecular Cork Effect

Journal Article Darby, Matthew T. ; Lucci, Felicia R. ; Marcinkowski, Matthew D. ; ... - Journal of Physical Chemistry. C

Pt-based materials are used extensively in heterogeneous catalytic processes, yet they are notoriously susceptible to poisoning by CO. In contrast, highly dilute binary alloys formed of isolated Pt atoms in a Cu metal host, known as PtCu single-atom alloys (SAAs), are more resilient to CO poisoning during catalytic hydrogenation reactions. In this article, we describe how CO affects the adsorption and desorption of H₂ from a model PtCu(111) SAA surface and gain a microscopic understanding of these species’ interaction at the Pt atom active sites. By combining temperature-programmed desorption and scanning tunneling microscopy with first-principles kinetic Monte Carlo, we identifymore »« less

Effect of Collective Dynamics and Anharmonicity on Entropy in Heterogenous Catalysis: Building the Case for Advanced Molecular Simulations

Journal Article Collinge, Greg ; Yuk, Simuck F. ; Nguyen, Manh-Thuong ; ... - ACS Catalysis

In this paper, we present a perspective on the computational determination of entropy and its effects and consequences on heterogeneous catalysis. Special attention is paid to the role of anharmonicity and the deviations from the standard harmonic oscillator approximations which can fail to provide a reliable assessment of entropy. To address these challenges, advanced methodologies are needed that can explicitly account for these thermodynamic drivers through the appropriate statistical sampling of reactive free energy surfaces. We discuss where anharmonicity should be expected, where it has been observed from a theoretical perspective, and the methods currently employed to address it. Wemore »« less

Effects of coadsorbed atomic oxygen on the electron-stimulated desorption of neutral NO from Pt(111)

Journal Article Burns, A R ; Stechel, E B ; Jennison, D R ; ... - Physical Review, B: Condensed Matter; (United States)

We examine the effects of an electronegative coadsorbate on the electron-stimulated-desorption (ESD) yield and desorbate energies (translational and internal) of a chemisorbed molecule. Specifically, we use laser resonance-ionization spectroscopy to characterize the ESD of neutral NO from a Pt(111) surface precovered with atomic oxygen. With increasing oxygen coverage (up to 0.75 monolayer), we observe the following for the NO desorbate: (1) an exponential increase in specific yield, (2) increased translational energy, (3) decreased vibrational energy, (4) decreased rotational energy, and (5) a growing propensity to produce the upper spin-orbit level of the spin-orbit-split electronic ground state. The first three observationsmore »« less

Optical spectroscopy and scanning tunneling microscopy studies of molecular adsorbates and anisotropic ultrathin films. Final report

Technical Report Hemminger, J C

The bonding, chemistry and ordering of molecular adsorbates on well defined single crystal surfaces and in ultrathin films was to be studied in an effort to develop sufficient fundamental understanding to allow the controlled preparation of anisotropic ultrathin films of organic monolayers. In this research the authors combine the use of optical probes (Raman spectroscopy, laser induced thermal desorption with Fourier transform mass spectrometry detection) with scanning tunneling microscopy (STM) and conventional methods of UHV surface science (Auger electron spectroscopy, x-ray photoelectron spectroscopy, low energy electron diffraction, and thermal desorption spectroscopy). The conventional surface probes provide well tested methods formore »« less

Neural Network Sampling of the Free Energy Landscape for Nitrogen Dissociation on Ruthenium

Journal Article Lee, Elizabeth Y. ; Ludwig, Thomas ; Yu, Boyuan ; ... - Journal of Physical Chemistry Letters

In heterogeneous catalysis, free energy profiles of reactions govern the mechanisms, rates, and equilibria. Energetics are conventionally computed using the harmonic approximation (HA), which requires determination of critical states a priori. Here, we use neural networks to efficiently sample and directly calculate the free energy surface (FES) of a prototypical heterogeneous catalysis reaction—the dissociation of molecular nitrogen on ruthenium—at density-functional-theory-level accuracy. We find that the vibrational entropy of surface atoms, often neglected in HA for transition metal catalysts, contributes significantly to the reaction barrier. The minimum free energy path for dissociation reveals an “on-top” adsorbed molecular state prior to themore »« less
