Well-Dispersed Bimetallic Nanoparticles

摘要: Studies on metal nanoparticles have been intensively carried out from a wide variety of scientific and practical interests [1–8]. These consist several tens or hundreds atoms in each one. Thanks to this limitation particle size number atoms, show their own properties, which can be classified by the terms “quantum effect”, “nanoscopic effect” “nanosize effect”. This introduces quite high population located surface area. For example, 1.5-nm sized noble 55 (Fig. 4.1). In case, 42 (76.4% total atoms) are area but only 13 (23.6%) inner core. Atoms chemically unsaturated they dominant nanoparticle systems 4.2). phenomenon special properties different bulk, dominated saturated
