PREVIOUS APPROACHES TO CATALYSIS FROM THE SURFACE SCIENCE 

There are in the hteratuie several reviews about this topic (see for example Refs. 20-22). In this Section we discuss oidy the more relevant aspects related to the concepts that can be apphed to electrochemical systems. 

In the case of coin metals like Au and Ag (see Fig. 3), the center of the d band lies too low and thus both bonding and antibonding levels are situated below the Fermi level and in consequence are filled making the interaction repulsive. The opposite happens with Pt, which is a good catalyst. In this case, the center of the band is situated near the Fermi level, and thus the bonding
