Due to their outstanding and tunable electronic properties, platinum nanowires have the potential to be used in the development of advanced devices. The quantum confinement effect of the electrons and the increased surface area to volume ratio found in nanowires give them unique physical and chemical characteristics. However, until recently, the advance in the utilization of nanowires had been relatively slow due to the difficulties associated with the synthesis of such nanostructures with well-controlled size. This dissertation shows how zeolites could be used for the synthesis of platinum nanowires as well as other nanostructures such as nanoclusters, multipods and nanoflower-like structures by using different precursors and reduction methods. In particular this dissertation shows the development of a new synthesis protocol that allows the formation of platinum nanowires in zeolites via solid state reduction. In addition to the synthesis and characterization of the nanostructures this dissertation includes a multivariate statistical analysis of the results using the method Project to Latent Structures Discriminant Analysis.
