dc.description.abstract | The 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 |
