Abstract

Two kinds of adsorbed N atoms exist on a Pt 0.25 Rh 0.75 (100) surface. One desorbs at 490 K and the other desorbs at 650 K. The former reacts with H 2 at 400 K, but the latter does not. It is supposed that the adsorption of these two N atoms is responsible of the surface composition, ratio of Pt and Rh.
