Abstract:
Nanostructured metal oxides have pulled in huge amount of interest lately because of their
distinctive electrical, mechanical and optical properties at the point when their basic element size
is down to nanoscale. There are a variety of metal oxide nanostructures, extending from
nanoparticles, nanowires, nanotubes and nanoporous structures. In our review, we only
concentrate on nanowires of titanium dioxide (TiO2) grown on titanium alloys. In this thesis an
innovative and simple strategy for the creation of nanowires titanium dioxide (TiO2) by thermal
oxidation of titanium alloy and commercially pure titanium is presented. Through the
experiments, it was determinesd that the formation of nanowires depends on the oxidation
temperature and Flow rate of Argon gas. Also the mechanism behind the production of the
nanowires has been discussed. Many applications of nanowires using this method are presented
and future works are suggested. For example, Ti-6%Al-4%V (Ti64) is widely used for
biomaterial applications and by growing nanowires on it; the cell adhesion is improved which is
used on medical implants. Also gas sensors fabricated with nanowires for detection purposes is
extensively preferred as it improves surface to volume ratios, sensitivity, selectivity, power
consumption and response time.
This thesis will also give a light to the designing of the experimental apparatus, and the problems
faced during the setup. Main aim was to construct a simple, reproducible, scalable and cheap
method to create nanowires.
