The idea behind this book is to combine the size dependent and alloying induced modifications in the hydrogenation properties to achieve improved Pd-H interaction. To tailormade the size selected Pd, Pd-Ag and Pd-Cu nanoparticles, Gas Phase Synthesis technique is used because of its better size control over other techniques. The morphological, structural and electronic properties of the above nanoparticles were studied using XRD, TEM and XPS. TEM confirms the monodisperse and crystalline nature of the nanoparticles. XPS shows that the core level and valance band binding energies increase on...
