TL;DR: Colloidal bimetallic nanocrystals are used to produce catalysts where the active and promoter phases are colocalized to a fine extent and some metals inhibit the sintering of the active Pd metal phase, while others increase its intrinsic activity compared to a monometallic Pd catalyst.

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.

TL;DR: In this paper, a modular approach for the systematic synthesis of polymer-nanocrystal hybrids, where palladium nanocrystals are encapsulated within tunable microporous polymer layers, is presented.

TL;DR: Overall, across particle sizes and alloy compositions, increased catalytic activity to Pd oxidation is related, thus shedding light on previous contrasting results related to the methane combustion activity of these catalysts.
