Single-atom Pt in intermetallics as an ultrastable and selective catalyst for propane dehydrogenation

摘要

Four different surface terminations of PtGa:A(111) viewed along [101] direction (ball model). Diagonal view of Pt and Pt termination (space-filling model). Pt is highlighted with black color. Catalyst design by Pb deposition to block the Pt (and Ga ) sites and to keep the Pt sites available.
