Physical Review B
The interactions of O, HO, CO, CO, NO, NO, NO, HS and SO with evaporated nickel films have been studied over temperatures of 77 to 400 K and adsorbate pressures of 10-8 Torr to several Torr. The reactions range from reversible adsorption at 77 K only (CO) to complex molecular and dissociative adsorptions leading to surface phases of a few monolayers thickness (O, NO, NO). With the aid of gas-phase data and the spectra of some of the molecules adsorbed on gold at 77 K it is possible to separate non-dissociative and dissociative adsorptions. Proposals concerning the products of dissociation can be made, though for NO, NO and SO the reactions are very complex.
