Journal ArticleDOI
Isolated Metal Atom Geometries as a Strategy for Selective Heterogeneous Hydrogenations
Georgios Kyriakou,Matthew B. Boucher,April D. Jewell,Emily A. Lewis,Timothy J. Lawton,Ashleigh E. Baber,Heather L. Tierney,Maria Flytzani-Stephanopoulos,E. Charles H. Sykes +8 more
TL;DR: Desorption measurements in combination with high-resolution scanning tunneling microscopy show that individual, isolated Pd atoms in a Cu surface substantially lower the energy barrier to both hydrogen uptake on and subsequent desorption from the Cu metal surface.
Journal ArticleDOI
Highly active copper-ceria and copper-ceria-titania catalysts for methanol synthesis from co2
Jesús Graciani,Kumudu Mudiyanselage,Fang Xu,Ashleigh E. Baber,Jaime Evans,Sanjaya D. Senanayake,Dario Stacchiola,Ping Liu,Jan Hrbek,Javier Fernández Sanz,José A. Rodriguez +10 more
TL;DR: Experimental and theoretical evidence is presented for a completely different type of site for CO2 activation: a copper-ceria interface that is highly efficient for the synthesis of methanol.
Journal ArticleDOI
Importance of the Metal–Oxide Interface in Catalysis: In Situ Studies of the Water–Gas Shift Reaction by Ambient‐Pressure X‐ray Photoelectron Spectroscopy
Kumudu Mudiyanselage,Sanjaya D. Senanayake,Leticia Feria,Shankhamala Kundu,Ashleigh E. Baber,Jesús Graciani,Jesús Graciani,Alba B. Vidal,Stefano Agnoli,Jaime Evans,Rui Chang,Stephanus Axnanda,Zhi Liu,Javier Fdez. Sanz,Ping Liu,José A. Rodriguez,Dario Stacchiola +16 more
TL;DR: It is shown herein how sites associated with a metal–ceria interface can dramatically change the reaction mechanism of the water–gas shift reaction (WGSR; CO + H2O!H2 + CO2).
Journal ArticleDOI
Experimental demonstration of a single-molecule electric motor
Heather L. Tierney,Colin J. Murphy,April D. Jewell,Ashleigh E. Baber,Erin V. Iski,Harout Y. Khodaverdian,Allister F. McGuire,Nikolai Klebanov,E. Charles H. Sykes +8 more
TL;DR: It is reported that a butyl methyl sulphide molecule adsorbed on a copper surface can be operated as a single-molecule electric motor using Electrons from a scanning tunnelling microscope to drive the directional motion of the molecule in a two-terminal setup.
Journal ArticleDOI
Hydrogen Dissociation and Spillover on Individual Isolated Palladium Atoms
TL;DR: This study reveals that individual, isolated Pd atoms can promote H2 dissociation and spillover onto a Cu(111) surface, but that the same mechanism is not observed for an identical array of Pd atom in Au(111).
