dc.description.abstractThe main aim of this project was to develop new 1D metal based nanomaterials and explore their use for potential applications in catalysis. This work involves the synthesis, characterisation, and application of new AuAg ultrathin nanowires and studies the use of vortexing as method of inducing chirality in large aspect ratio Ag nanowires. Chapter 1 provides a literature review and background information on the synthesis and application of 1D nanomaterials, particularly ultrathin materials. Topics such as chirality, plamonics and fuel cells are also discussed in detail. In addition the aims of the project are also outlined. Chapter 2 provides information on the synthetic and experimental protocols used in this work. The characterisation techniques and equipment used are also detailed. Chapter 3 describes a tunable synthesis of water soluble ultrathin AuAg nanowires using a novel protocol. The influence of various parameters in this synthesis and further optimization our protocol using temperature control are investigated. A new ultrathin AuAg nano-necklace structure was also synthesised and characterised. The ultrathin 1D AuAg nanomaterials were further used as catalysts for the electrooxidation of ethylene glycol.The chiral modification of 1D ultrathin AuAg nanomaterials using a facile ligand exchange method is detailed in Chapter 4. In chapter 5 we investigate the use of our ultrathin AuAg nanowires as templates for the synthesis of novel 1D Pt, Rh, and RhPt nanomaterials. The resulting Pt and RhPt nanomaterials were further used as anodic catalysts for the electro-oxidation of methanol and formic acid. Chapter 6 is dedicated to studying the influence of stirring on the observed chiroptical activity of large aspect ratio Ag nanowires. This chapter also includes the development of new chiral plasmonic-excitonic Ag nanowire@ quantum dot hybrid nanostructures. Finally, chapter 7 outlines the overall conclusions and details future plans and some preliminary work.en
