Synthesis and Characterization of Nanostructured Materials for Hydrogen

Storage Applications

The technologies for hydrogen storage constitute the critical point for the development of transport systems based on H2. In recent years the interest for hydrogen storage in solid system has increased and in particular in some metals and intermetallic compounds able to form phase hydride capable of reversibly absorb large quantities of hydrogen at low temperatures. In this work a simple synthesis for palladium clusters has been developed. Monodispersed palladium cluster can be produced by reduction of K2PdCl4 in ethylene glycol (EG), that is known as alcoholic reduction, using polyvynilpyrrolidone (PVP) as polymeric surface stabilizer. The nano-sized palladium particles can be isolated in a polymer-embedded form, which is free from aggregates and characterized by a polyhedral shape. The future activities will involve the development of lightweight materials for hydrogen storage as the synthesis of others nanostructured materials (for examples nanosized Magnesium) by different approaches and preparation of metal-polymer nanocomposites stabilized based on palladium and/or other noble metals able to determine the phenomenon of spill-over.
