(a) Adsorption in wire
(b) Adsorption in graphite
Figure 11: Configuration of the most stable adsorption of hydrogen (blue) on the wire (a) and at the edge of graphite (b) of GSW. The corresponding energies in eV are shown below. On the wire, for both metals, the adsorption is on top. On the graphite edge, the adsorption is in the same plane in the case of gold and above it in the case of platinum.
