Graphical Abstract
  • tip is washed with isopropanol, then by Milli-Q water and dried with pure nitrogen gas. In the third step, the etched tip is cut to length and glued on by hand with silver epoxy to the free end of the tuning fork prong. Tip lengths are cut to approximately 200 μm to prevent unwanted potential lateral
  • hydrocarbons CnH2n+2, with water as byproduct [24]. We have investigated the reaction on Co nanoparticles deposited on an Al2O3 support, grown on a NiAl(110) single crystal. The NiAl(110) surface has been prepared by repeated cycles of Ar-ion sputtering (3 μA, 1 kV, 30 min) at room temperature followed by

Hereafter, the temperature decreases, until reaching 490 K, where the reaction completely stops and the number of counts starts to significantly decrease. At 490 K, at which point the Co
