Hydrogen Bonding of Ammonia with (H,OH)-Si(001) Revealed by Experimental and Ab Initio Photoelectron Spectroscopy

Combining experimental and ab initio core-level photoelectron spectroscopy (periodic DFT and quantum chemistry calculations), we elucidated how ammonia molecules bond to the hydroxyls of the (H,OH)-Si(001) model surface at a temperature of 130 K. Indeed, t ...

C-H Bond Activation by an Isolated Dinuclear U(III)/U(IV) Nitride

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic

Synthetic studies of bimetallic uranium nitride complexes with the N(SiMe3)(2) ligand have generated a new nitride complex of U(III), which is highly reactive toward C-H bonds and H-2. Treatment of the previously reported U(IV)/U(IV) nitride complex [Na(DM ...

Essential role of oxygen vacancies of Cu-Al and Co-Al spinel oxides in their catalytic activity for the reverse water gas shift reaction

Ursula Röthlisberger, Jeremy Luterbacher, Oliver Kröcher, Pascal Alexander Schouwink, Murat Kiliç, Florent Emmanuel Héroguel, Alimohammad Bahmanpour, Christophe Jean Baranowski

CO2 catalytic hydrogenation to CO will likely be an important part of CO2 mitigation and valorization processes. Recently, we have developed materials containing surface-formed Cu-Al spinel that act as active and stable catalysts for this reaction. Here, t ...

Electrochemical reconstruction of ZnO for selective reduction of CO2 to CO

Andreas Züttel, Emanuele Moioli, Wen Luo, Jie Zhang, Kun Zhao, Qin Zhang

Electrocatalytic conversion of CO2 to valuable chemicals is a highly promising route to close the carbon cycle. Herein, Zn catalysts derived from electrochemical reconstruction of ZnO materials are presented as efficient CO2-to-CO catalysts. We found that ...

Partial Hydrogenation of 2-Methyl-3-butyn-2-ol over Pd/ZnO: Effect of Reduction Temperature on Alloy Formation and Catalytic Response

Lioubov Kiwi, Fernando Cardenas Lizana

We have investigated the catalytic effect of the beta-phase PdZn alloy on selective gas-phase hydrogenation of 2-methyl-3-butyn-2-ol over Pd/ZnO using Pd/Al2O3 as a benchmark. Activation (in H-2) of Pd/ZnO to 973 K generated a beta-phase PdZn alloy (from X ...

Incompleteness of Atomic Structure Representations

Michele Ceriotti, Sergey Pozdnyakov, Michael John Willatt

Many-body descriptors are widely used to represent atomic environments in the construction of machine-learned interatomic potentials and more broadly for fitting, classification, and embedding tasks on atomic structures. There is a widespread belief in the ...

Site Selective Detection of Methane Dissociation on Stepped Pt Surfaces

Rainer Beck, Ana Gutiérrez González

We report a combined experimental and theoretical study comparing methane dissociation on three di erent platinum surfaces Pt(111), Pt(211), and Pt(110)-(1 × 2). Re ection absorption infrared spectroscopy (RAIRS) was used to detect chemisorbed methyl speci ...

Model-assisted identification of solid oxide cell elementary processes by electrochemical impedance spectroscopy measurements

Jan Van Herle, Stefan Diethelm, Arata Nakajo, Priscilla Caliandro

Electrochemical Impedance Spectroscopy (EIS) is extensively used to characterize Solid Oxide Cells (SOCs) to extract information on the elementary loss mechanisms. However, these individual mechanisms usually overlap in the frequency domain, requiring dedi ...
