Title: Co Chemisorption On Pd; Effect Of Segregated Phosphorus
Author: Sundaram V.S.

Abstract: Auger Spectroscopy and Thermal Desorption Spectroscopy were used to determine the effect of P on the activation energy for desorption of CO from a Pd foil. The CO chemisorption energy on a clean Pd surface was coverage dependent, with a low coverage value of 32 kcal mole, in agreement with results for monocrystal low index faces. On a P segregated surface, however, a coverage independent CO chemisorption energy of 26 kcal mole was observed. From the shape of the P(L23VV) Auger line, it is concluded that segregated P is not in its elemental form. © 1982.
