SURFACE STATES IN PURE PALLADIUM.
LAWRENCE UNIV APPLETON WIS DEPT OF CHEMISTRY
Magnetic susceptibility studies on small crystal 112A 500A palladium blacks and studies of the interaction of adsorbed nitric oxide with palladium surfaces through magnetic susceptibility and standard adsorption techniques were made. The observed dependence of the magnetic susceptibility of palladium on particle size is consistent with a postulate of a band of electronic surface states lying slightly above the bulk 4-d band. Sorption studies indicate that nitric oxide is adsorbed at room temperatures to slightly more than monolayer coverage in both a physisorbed and a weakly energetic chemisorption state whose precursor is the physisorbed state. In addition, a complex cooperative electronic rearrangement apparently occurs over a small temperature range around room temperature and at monolayer coverage. Author
