| Research Abstract |
Adsorption of NO and its reduction with H_2 were performed on Pt_3Co(111) surface. It is Known that Pt is inactive surface for the adsorption of N, but the (111) surface of Pt_3Co is covered with the islands of N atoms. By depositing ^<14>N and ^<15>N on the surface, the isotopic mixing in N_2 was studied. Desorbed nitrogen molecules are mainly ^<14>N_2 and ^<15>N_2, which indicates isolated islands of ^<14>N and ^<15>N species.
NO + H_2 reaction yielded N_2, H_2O and NH_3. Pressure dependence was as follows; N_2 formation depends on zero order with respect to H_2 pressure and 1/2 order to NO, while that for the formation of NH_3 was zero order to NO and 1/2 order to H_2.
