| Nanostructured transition metal nanoparticles are of great interest from both fundamental and practical view points because of the quantum size effect, which is derived from the dramatic reduction of the number of free electrons. [Halperin, 1986; Schmid, 1994] Volokitin et al. have found that the quantum size effect strongly affected the thermodynamics of the metal nanoparticles. [Volokitin et al., 1996; Colvin et al., 1994; Andres et al., 1992] Platinum is considered one of the best electrocatalyst for low temperature reactions in a H2/O2 fuel cell. Palladium is an element of the platinum group metals and it has similar chemical properties. Nanoparticles(Nps) are of great interest because of the modification of properties observed due to size effects, modifying the catalytic, electronic, and optical properties of the monometallic Nps. Interest in platinum Nps derives mostly from the importance of highly dispersed platinum and palladium in catalysis. [Colvin et al., 1994; Andres et al., 1992] They have been concretly applied to catalysts[Lewis, 1993] for hydrogenation of olefins and dienes,[Hirai et al., 1986; Teranishi, 1996] hydration of acrylonitrile to acrylamide,[Toshima & Wang 1994] photogeneration of hydrogen from water,[Bard, 1980] and reduction of carbon dioxide,[Willner et al., 1987; Toshima et al.,1995] | |
