Catalytically Active Gold: From Nanoparticles to Ultrathin Films
Mingshu Chen,D. Wayne Goodman +1 more
TL;DR: This is the first report of Au completely wetting an oxide surface and demonstrates that ultrathin Au films on a oxide surface have exceptionally high catalytic activity, comparable to the activity observed for Au nanoparticles.

TL;DR: In this article, the authors demonstrate that isolated Au single atoms dispersed on iron oxide nanocrystallites (Au-1/FeOx) are much more sinteringresistant than Au nanostructures, and exhibit extremely high reaction stability for CO oxidation in a wide temperature range.

TL;DR: An aberration-corrected, environmental transmission electron microscopy method was applied to show that adsorbed carbon monoxide molecules caused the 100 facets of a gold nanoparticle to reconstruct during CO oxidation at room temperature, and the energetic favorability of this reconstructed structure was confirmed.

Highly active surfaces for CO oxidation on Rh, Pd, and Pt
TL;DR: The rate of CO oxidation on Pt-group metals at temperatures between 450 and 600 K and pressures between 1 and 300 Torr increases markedly with an increase in the O2/CO ratio above 0.5.
