Temperature influence on the reactivity of plasma species on a nickel catalyst surface: An atomic scale study

- Reactivity on Ni(1 1 1) was studied as a function of temperature.
- Substantial H2 formation is obtained at 1400 K and 1600 K.
- H2 molecules are the most frequently formed species at 1600 K.
- Carbon diffusion into lower subsurface layers starts at a temperature of 1200 K.
