Reversible hydrogenation of surface N atoms to form NH on Pt(111)

Article Abstract:

The formation and dissociation chemistry of the NH species on Pt(111) is characterized with reflection absorption infrared spectroscopy and temperature programmed desorption. Irradiation of chemisorbed bilayer of ammonia with a 100 eV electron beam at 85 K leads to a mixture of NH, N and H on the surface.

High pressure scanning tunneling microscopy study of CO poisoning of ethylene hydrogenation on Pt(111) single crystals.

Article Abstract:

A study was conducted on the poisoning effects of CO on ethylene hydrogenation by scanning tunneling microscopy on Pt(111) and Rh(111) single-crystal surfaces in the mtorr range at room temperature. The rates of ethylene hydrogenation on both metal surfaces were shown to drop on the addition of CO.

Surface chemistry of CN bond formation from carbon and nitrogen atoms on Pt(111)

Article Abstract:

The mechanism of CN bond formation from CH3 and NH3 fragments adsorbed on Pt(111) was investigated with reflection absorption infrared spectroscopy (RAIRS). Cyanide formation is observed from the reaction of adsorbed N atoms and carbon produced from the dissociation of ethylene.
