Although there are only a few known examples of supported single-atom catalysts, they are
unique because they bridge the gap between homogeneous and heterogeneous catalysis.
Here, we report the CO oxidation activity of monodisperse single Pt atoms supported on an
inert substrate, θ-alumina (Al2O3), in the presence of stoichiometric oxygen. Since CO
oxidation on single Pt atoms cannot occur via a conventional Langmuir–Hinshelwood
scheme (L–H scheme) which requires at least one Pt–Pt bond, we carried out a first …

Although there are only a few known examples of supported single atoms, they are unique
because they bridge the gap between homogenous and heterogeneous catalysis. The metal
center is single supported atoms can be isoelectronic with their homogenous catalyst
counterpart and may allow mechanistic pathways normally seen in homogenous catalysts.
Here, we report CO oxidation activity of mono-disperse single Pt atoms supported on an
inert substrate,-alumina (Al2O3), in the presence of stoichiometric oxygen. Since CO …
