An Electron Spectroscopy Study of Ammonia Adsorption on Clean and Oxidized Aluminum.
Abstract
Photoelectron spectra for ammonia adsorbed in submonolayer and multilayer amounts on clean and oxidized aluminum have been measured and interpreted. Uptake at 128K is dominated by weak molecular adsorption and saturates at submonolayer amounts whereas at 106K multilayers can be formed. On oxidized A1, as compared to clean, the saturation amount of adsorbed NH3 is larger and it is more tightly held. On clean A1, there is good evidence that NH3 tends to be physisorbed with the major bonding arising between the dipole of NH3 and the image dipole induced in the metal.(Author)
