Extended Data Fig. 7: DFT and sintering models.

From: Templated encapsulation of platinum-based catalysts promotes high-temperature stability to 1,100 °C

Extended Data Fig. 7

a, Side-on views of the atomic models optimized for the interfaces of Pt(100) and Pt(111) with the γ-Al2O3(100) surface. b, Illustration of sintering models and underlying assumptions: Left: No diffusion limitations lead to immediate equilibration within the gas phase and thus a constant background pressure. Right: Significant diffusion limitations through the encapsulating material lead to local equilibration between particle and gas phase for each particle, so that locally the equilibrium pressure is established.
