| Name | AgPd in 1 mbar O2 74°C (cooling) |
| Ex situ preparation | Quantitative amounts of the Ag (slugs 3×3mm, 99.99%) and Pd (granules <7mm, 99.95%) purchased from EvoChem were melted in a light oven, with a four times re-melting process for homogenization. Afterwards the alloy was cold-rolled to a 1.6 mm thick foil and then annealed for 6h at 800°C for grain size growth. The foil was cut into smaller pieces and polished, with incrementally finer grid, down to a 1 µm using diamond suspension. |
| In situ preparation | cleaned by Ar+ sputter and annealing cycles. After Ar+ sputter cleaning the sample was heated in 0.5 mbar H2 at 450°C for 2 h. For the oxidation experiment the sample was heated in 1 mbar O2 from 70°C-400°C with a ramping speed of 0.3°C/min |
