In any case, the treatment of the catalyst results in a more selective (regarding the formation of primary amine) hydrogenation of nitriles. This effect could be explained on a molecular basis by electronic (work function) and/or steric effects by strongly adsorbed species that function to partition the wide-open active surface of Ni and Co catalysts into smaller active sites composed of a controlled number of... 

This equation states that the ratio of the rates of ion evaporation to atom evaporation is determined by the temperature and by the difference between the electron work function and the ionization potential it depends only indirectly on ipj, J, Np, and N. This conclusion agrees with thermodynamical reasoning. 

The connection between electronic work function and catalytic activity was shown some time ago, especially by Suhrmann (1-4) and Czesch (1), who found a simple relation between the changes of the work functions of different metal surfaces upon adsorption of H atoms, and the catalytic activities of such surfaces for the recombination of H atoms. 

Since the electron work functions and the specific surface energies of different planes of the same crystal may have different values, it would be interesting to study the electronic interaction during adsorption of foreign molecules on monocrystals. Investigations of monocrystals, however, encounter many difficulties therefore, one has to restrict oneself in general to poly crystalline surfaces, which also give remarkable results because the force of interaction essentially depends on the nature of the metal and differs for the same metal from one species of adsorbed molecules to the other. 

The volcano curve is based on the performance of simple metals, and the heat of adsorption is the factor which turns out to be responsible for the change in activity from metal to metal. However, the difficult issue from a theoretical point of view is the identification of the properties of metals which govern the magnitude of the adsorption heat. A number of correlations have been proposed, based on different electronic or structural properties of metals [56-65]. The aim has been to establish a reactivity scale from which predictions on the behaviour of unknown materials could be made. It appears that the correlation between the electron work function and the activity of metals for hydrogen evolution is very likely to be the most reliable [54,66], since it has been verified several times by different authors independently [57,62,67],...

The various energetic, factors which determine the value of E i are the sublimation energy of the metal, the ionization potential of the atom, the electronic work function and the hydration, or other complexiug energy of the ion. These factors have been discussed extensively by Kieffer (7), Piontelli (8) and... 

As foreseen from the discussion of Section III.5, the contributions to the surface potential from the overspill of the electrons perpendicularly to the metal surface and the smoothing by a lateral flow of electrons from high-ionic-density regions to low-ionic-density ones, explain the decrease of the electronic work function and the pzc from smooth to atomically stepped surfaces. 

The relationship between the electron work function and the over-all activity and selectivity of oxidation may be seen from Fig. 17. The...
