Supported atomic clusters with uniform metal sites and definite low-nuclearity are
intermediate states between single-atom catalysts (SACs) and nanoparticles in size …

Conspectus Heterogeneous catalysis is at the heart of the chemical industry. Being able to
tune and design efficient catalysts for processes of interest is of the utmost importance, and …

With increasing interest in atomically dispersed and sub-nanometer Pt and Pt–Sn cluster
catalysts for propane dehydrogenation (PDH), understanding structure–property …

Supported sub-nano clusters hold great promise as economical and highly active catalysts.
However, they tend to deactivate rapidly by poisoning and sintering, impeding their …

Catalytic systems are complex and dynamic, exploring vast chemical spaces on multiple
timescales. In this perspective, we discuss the dynamic behavior of fluxional, heterogeneous …

We present a combined experimental/theoretical study of Pt n/SiO2 and Pt n Sn x/SiO2 (n=
4, 7) model catalysts for the endothermic dehydrogenation of hydrocarbons, using the …

X-ray absorption near edge structure (XANES) spectroscopy is widely used for operando
catalyst characterization. We show that, for highly fluxional supported nanoclusters, the …

Using Pt in the form of subnanometer dispersed clusters is a way to save precious metals in
catalysis, but making such clusters stable against sintering is an uphill battle. Sn is a known …

The selective dehydrogenation of hydrocarbons and their functionalized derivatives is a
promising pathway in the realization of endothermic fuel systems for powering important …

Size selection was demonstrated to suppress Ostwald ripening of supported catalytic
nanoparticles. When the supported clusters are subnanometer in size and highly fluxional …
