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
Water-Gas Shift Reaction on a Highly Active Inverse CeOx/Cu(111) Catalyst: Unique Role of Ceria Nanoparticles
José A. Rodriguez,Jesús Graciani,Jaime Evans,Joon B. Park,Fan Yang,Dario Stacchiola,Sanjaya D. Senanayake,Shuguo Ma,Manuel Perez,Ping Liu,Javier Fernández Sanz,Jan Hrbek +11 more
TL;DR: The scheme (bot-tom left) was composed using the line profile indicated by the greenline shown near the middle of the top right image, and the work was performed by the US Department ofEnergy, Office of Basic Energy Sciences, under contract DE-AC02-98CH10886.
Journal ArticleDOI
High catalytic activity of Au/CeOx/TiO2(110) controlled by the nature of the mixed-metal oxide at the nanometer level
Joon B. Park,Jesús Graciani,Jaime Evans,Dario Stacchiola,Shuguo Ma,Ping Liu,Akira Nambu,Javier Fernández Sanz,Jan Hrbek,Jose Rodriguez +9 more
TL;DR: The exploration of mixed-metal oxides at the nanometer level may open avenues for optimizing catalysts through stabilization of unconventional surface structures with special chemical activity through structural promotion in catalysis.
Journal ArticleDOI
Gold, Copper, and Platinum Nanoparticles Dispersed on CeOx/TiO2(110) Surfaces: High Water-Gas Shift Activity and the Nature of the Mixed-Metal Oxide at the Nanometer Level
Joon B. Park,Jesús Graciani,Jaime Evans,Dario Stacchiola,Sanjaya D. Senanayake,Laura Barrio,Ping Liu,Javier Fdez. Sanz,Jan Hrbek,José A. Rodriguez +9 more
TL;DR: The high catalytic activity of the M/CeO(x)/TiO(2)(110) surfaces reflects the unique properties of the mixed-metal oxide at the nanometer level.
