Abstract: Metal cluster structures composed of tens of atoms represent a new class of catalysts with potentially superior catalytic activity and durability compared with those of other conventional catalysts. However, controlling the number of constituent atoms in clusters and achieving high-density loading on supports remain challenging. We reduce PtCl42− with methanol to create platinum atoms forming strongly anchored platinum clusters with controlled atom counts on selected surfaces of alumina. We resolved the atomic structures of the platinum clusters and could correlate the degree of cluster-support interaction, catalytic activity, and durability with atom counts. We demonstrate the promise of this approach by developing platinum clusters that exhibit the highest catalytic performance per platinum usage reported to date for hydrogen production from the dehydrogenation of cyclic hydrocarbon hydrogen carriers. Editor's summary: Song et al. created strongly anchored clusters of platinum on alumina by reducing PtCl42− with methanol. They then used electron microscopy to show that clusters with the same 1-nanometer diameter could vary in total atom count by a factor of three. X-ray absorption spectroscopy showed that clusters with higher atom counts had stronger interactions with the support. For hydrogen production from cyclic hydrocarbons, clusters with fewer atoms had higher activity, but those with more atoms were more durable and selective. —Phil Szuromi [ABSTRACT FROM AUTHOR]
