要旨

The thermal decomposition of NH₃ was studied on the open Ru(1121) surface using high-resolution electron energy loss spectroscopy (HREELS) and thermal desorption spectroscopy (TDS). For small NH₃ coverages up to 0.25 of a monolayer, NH₃ decomposes completely during annealing of the sample. At higher coverages molecular desorption is also observed. The dehydrogenation gives rise to sharp peaks in the H₂ TD spectra. NH₂, NH, and N are identified using HREELS. A translational mode of NH₃ is observed at 15 meV.
