The study of bimetallic surfaces that consist of one noble metal and one or more inexpensive 3d transition metals has generated great interest in the field of catalysis because their electronic and chemical properties are completely different from those of the constituent metals [1], [2] and [3]. In general, an enhanced activity and selectivity have been obtained for these materials compared to the parent metals for various heterogeneous and electrochemical catalysis applications [4], [5], [6] and [7]. In addition, the lower cost due to the use of less expensive transition metals make these bimetallic surfaces promising materials for various applications including fuel cell related technolo
