Fluxional Behavior at the Atomic Level and its Impact on Activity: CO Oxidation over CeO$_{2}$-supported Pt Catalysts

  title={Fluxional Behavior at the Atomic Level and its Impact on Activity: CO Oxidation over CeO\$\_\{2\}\$-supported Pt Catalysts},
  author={Joshua L Vincent and Peter A. Crozier},
Reducible oxides are widely used catalyst supports that can increase oxidation reaction rates by transferring their lattice oxygen at the metal-support interface. The interfacial oxidation process is typically described in terms of a Mars-van Krevelen mechanism. However, many outstanding questions remain unanswered regarding the atomic-scale structure and dynamic meta-stability (i.e., fluxional behavior) of the interface during catalysis. Here, we employ operando transmission electron…

Atomic-resolution Operando and Time-resolved In Situ TEM Imaging of Oxygen Transfer Reactions Catalyzed by CeO2-supported Pt Nanoparticles
Oxygen transfer is a critical functionality in automotive exhaust control and clean energy conversion. In these applications, catalytically active metal nanoparticles (e.g., Pt) are often dispersed
Structural changes in noble metal nanoparticles during CO oxidation and their impact on catalyst activity
Operando TEM studies of Pd NPs during CO oxidation are presented, which show reversible changes in both structure and activity with temperature, and it is proposed that adsorbed CO molecules suppress the activity of PD NPs at lower temperatures by stabilizing low index facets and reducing the number of active sites.
Visualization of oscillatory behaviour of Pt nanoparticles catalysing CO oxidation.
To successfully explain the oscillations of CO oxidation catalysed by Pt nanoparticles, the model must contain the phenomenon of refacetting, and the nanoreactor approach can provide atomic-scale information that is specific to surface sites, which will improve the understanding of dynamic properties in catalysis and related fields.
Dynamic structure of active sites in ceria-supported Pt catalysts for the water gas shift reaction
It is found that the perimeter Pt0 − O vacancy−Ce3+ sites are formed in the active structure, transformed at working temperatures and their appearance regulates the adsorbate behaviors and the dynamic nature of this site is a key mechanistic step for the WGS reaction.

Control of Metal Nanocrystal Size Reveals Metal-Support Interface Role for Ceria Catalysts
Rate measurements are reported on samples in which the length of the ceria-metal interface was tailored by the use of monodisperse nickel, palladium, and platinum nanocrystals, and it is found that carbon monoxide oxidation inceria-based catalysts is greatly enhanced at the cia- metal interface sites for a range of group VIII metal catalysts.

Ensembles of Metastable States Govern Heterogeneous Catalysis on Dynamic Interfaces.
The catalytic interface should be viewed as an evolving statistical ensemble of many structures (rather than one structure), which flips the established paradigm and calls for a new theory, new modeling approaches, operando measurements, and updated design strategies.
