Metal clusters and nano-structures have attracted the attention of many researchers since metal clusters with closed electronic shells are extremely stable and can be used as building blocks for new materials. Specifically, nano-assemblies of metal clusters can potentially have application in a hydrogen energy production technology where a safe, compact and inexpensive system able to store a large amount of hydrogen is of crucial importance. In this project we will address the basic issues of the structural stability of light metal clusters, their adsorption capacity and reactivity with atomic and molecular hydrogen as well as their alloying, transport and thermal properties. This investigation aims to provide fundamental knowledge and, ultimately, directions for assembling the clusters and/or nanowires into stable nano-solids (i.e. solids made up of nanostructures) for application in novel hydrogen storage technology. Although we will particularly focus on nanostructures of Aluminium, the abundant, light, cheap, accessible and, hence, promising metal for use in hydrogen storage, the methodologies, approaches and theories developed here can be applied to other nano-materials. |
