Abstract

This study includes synthesis of CuO nanostructures with different morphologies, characterization,
and applications of CuO nanostructures (NSs) in the field of renewable energy and enhancing
thermal conductivity. Within this broad scope the thesis focuses on.
 Synthesis of CuO nanostructures with different morphologies and investigating the
correlation between the experimental parameters and resulting nanostructures.
 Enhancement the catalytic activity of the synthesized CuO nanostructures on the pyrolysis
of sugarcane bagasse (SCB), one of the approaches that is used in convertion of biomass
into bio fuels.
 Improving the thermal conductivity of the monoethylene glycol (MEG).
Solution- based methods (bottom-up approaches), such as hydrolysis and chemical precipitation
method have been used for the synthesis of CuO nanostructures, more information about crystal
structure, composition, shape, size, optical properties and surface area were revealed by means of
several techniques such as X-ray Diffraction (XRD), Transmission electron microscopy (TEM),
Scanning electron microscopy (SEM), UV-vis spectrophotometer, and Brunauer–Emmett–Teller
(BET). The produced NSs are aggregates with various assemblies, consisting of several rod-like
crystallites that are arranged by self-assembly processes. The resulting particles were found to be
spheres of CuO nanoparticles (5±1 nm), flower-like NSs (180-250 nm), bundles of rods with a
range of different sizes (350– 630 nm), and spindles-like assemblies (up to 1.3 micron).
