TL;DR: The results show that reaction selectivity can be heavily dependent on catalyst structure and that structural changes of the catalyst can occur even at low temperatures and can go unseen in materials with less defined structures.

TL;DR: In this article, the authors reveal the opposite process as a novel deactivation mechanism: nanoparticles rapidly lose activity by high-temperature nanoparticle decomposition into inactive single atoms, leading to severe loss of activity in as little as ten minutes.

TL;DR: In this article, the effect of adding platinum to palladium catalysts for methane combustion was investigated, and the results showed that at low temperatures and in the absence of steam, all bimetallic catalysts showed activity nearly identical with that of Pt/Al2O3, with much lower rates in comparison to that of the Pd/Al 2O3 sample.

TL;DR: A review of the principal methods to produce colloidal nanocrystals with a high level of control is reported, complemented by procedures for how to prepare active catalysts from these particles as discussed by the authors.

TL;DR: Through precise structural characterization, it is demonstrated that isolated atoms of Pd exist in the most active catalysts, allowing for the formation of reactive oxidizing species, likely hydroperoxide groups, responsible for selective oxidation while limiting oxygen dissociation and, thus, complete combustion.
