Unlike eq 1 above for the standard electrode potential, the work function equation has two terms which vary with size. The first is a negative shift dependent upon surface energy as in eq 1. The second term is a charging energy term, which gives a positive shift for smaller sizes. In a vacuum smaller Ag particles would have larger ionization potentials than bulk Ag - the second term dominates numerically. In water, dielectric screening makes the second term negligible with respect to the first. Smaller Ag particles would have lower ionization potentials than bulk Ag. Also note that in Plieth's equation 6b the charging energy term has a numerical factor of 3/8. It is now thought that this factor should be 1/2: see Makov, G.; Nitzan, A.; Brus, L. J. Chem. Phys. 1988, 88, 5076.
