The document presents a presentation on the synthesis and characterization of copper oxide nanomaterials. It discusses how copper oxide nanomaterials were synthesized using the sol-gel method, which involves dissolving copper nitrate in ethanol, adding sodium hydroxide dropwise to form a precipitate, filtering, drying, and annealing the material. It then characterizes the synthesized copper oxide using X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Fourier-transform infrared spectroscopy to analyze structure, morphology, composition and bonding. Finally, it discusses some potential engineering applications of copper oxide nanomaterials such as in catalysts, gas sensors, antibacterial agents, solar cells, and lubricants.

• NANO MATERIALS:
• Nanomaterials refer to materials that have been make at the nanoscale,
typically with dimensions ranging from 1 to 100 nanometers (nm). At this
scale, materials shows unique physical, chemical, and biological properties.
These properties grow due to the increased surface area-to-volume ratio,
quantum effects, and size-dependent phenomena.
• COPPER OXIDE:
• Copper(II) oxide or cupric oxide is an inorganic compound with the formula CuO. A
black solid, it is one of the two stable oxides of copper, the other being Cu2O
or copper(I) oxide (cuprous oxide).

CHARACTERIZATION OF
NANOMATERIALS:
• X-ray Diffraction (XRD)
• Fourier-transform Infrared Spectroscopy (FTIR)
• UV-visible Spectroscopy
• Scanning Electron Microscopy (SEM)
• Energy-dispersive X-ray Spectroscopy(EDX)

X-RAY DIFFRACTION (XRD):
17
XRD finds the geometry or shape of a
molecule using X-rays. It is a
nondestructive technique that provides
detailed information about the
crystallographic structure, chemical
composition, and physical properties
of a material

SCANNING ELECTRON MICROSCOPE (SEM):
The scanning electron microscope (SEM)
uses a focused beam of high-energy
electrons to generate a variety of signals at
the surface of solid specimens. Scanning
electron microscope (SEM) is one of the
most widely used instrumental methods for
the examination and analysis of micro- and
nanoparticle imaging characterization of
solid objects. One of the reasons that SEM
is preferred for particle size analysis is due
to its resolution of 10 nm, that is, 100 Å.

ENERGY DISPERSIVE SPECTROMETER(EDS):
Energy-dispersive X-ray
spectroscopy (also known
as EDS, EDX, or EDXA)
is a powerful technique
that enables the user to
analyze the elemental
composition of a desired
sample.

FOURIER-TRANSFORM INFRARED
SPECTROSCOPY (FTIR):
It is a technique used to obtain
an infrared spectrum of
absorption or emission of a
solid, liquid, or gas. The most
common use is in
the identification of unknown
materials and confirmation of
production materials(incoming
or outgoing).
