Application of nanomaterials in the field of
catalysts

• Nanomaterials play an important role in many
  chemical catalytic fields, which can control
  reaction time and increase reaction efficiency
  and speed. As catalysts, nanomaterials have many
  advantages. Nanomaterials have large specific
  surface area and many surface active centers, all
  of which provide the necessary conditions for
  catalysis. At the same time, the volume effect
  and surface effect of nanomaterials determine its
  good catalytic activity and catalytic
  selectivity. Compared with the general catalyst,
  nanocatalyst can greatly improve the reaction
  efficiency, and it reacts 10 to 15 times faster
  than the general catalyst. The metal
  nanoparticles can be directly used as catalysts,
  and the catalysts are mainly nano powders of
  noble metals such as Ag, Pd, Pt, Rh, etc., and
  base metals such as Fe, Co, Ni, and the like. The
  use of metal microparticles as a catalyst has
  good selectivity, and this selectivity is related
  to the particle size of the nanoparticles. In
  addition to chemical catalysis, photocatalysis
  and thermal catalysis of semiconductor
  nanoparticles have attracted widespread attention
  and have been applied in catalytic degradation of
  organic matter.

Application of nanomaterials in the preparation
of new engineering materials

• The small size effect of the nano material allows
  it to be sintered at a lower temperature to
  obtain a sintered body with excellent texture,
  and can maintain its good performance without any
  additives, so it can be used to prepare sintered
  materials at low temperature. At the same time,
  these nanomaterials can be used as activators in
  the relevant sintering process, which plays an
  important role in accelerating the sintering
  process, shortening the sintering time and
  lowering the sintering temperature. The small
  size effect and surface effect of nanomaterials
  not only reduce their melting point but also
  reduce the phase transition temperature, so that
  the melting point and phase transition
  temperature of different materials can be closer
  to each other and solid state reactions can be
  performed at low temperatures. Different kinds of
  nano-ceramic powders can be used to produce
  nano-ceramics with dense texture and excellent
  performance at low temperature and low pressure.
  Nano-ceramics have excellent properties such as
  good plasticity, high hardness, high temperature
  resistance, wear resistance, high susceptibility
  and coercivity, and low magnetic loss.

Application of nanomaterials in the field of
magnetic materials

• Magnetic materials are key materials for the
  storage, processing and transmission of
  information. In recent years, with the rapid
  development of information, the performance of
  recording medium materials, especially the
  recording density, has been improved. The
  recording medium material with high recording
  density is closely related to ultrafine
  particles. If ultrafine particles are used as the
  recording unit, the recording density can be
  greatly improved. Because the nano magnetic
  particles have a single magnetic domain structure
  and high coercive force, using it to make a
  magnetic recording material can improve the
  signal-to-noise ratio of the magnetic recording
  material, thereby improving image quality.

Application of nanomaterials in the field of
coatings

• Due to its unique photocatalytic function,
  nanomaterials have a strong decomposition and
  elimination effect on toxic gases in the air. The
  low surface tension, strong adhesion, and
  excellent self-cleaning function make the
  nano-materials suitable for exterior wall
  coatings of buildings. Because the size of
  nanometers is much smaller than the wavelengths
  of infrared and radar waves, the transmission of
  nanoparticles to these waves is much stronger
  than that of conventional materials, and the
  reflectance of infrared and radar waves is
  greatly reduced. Therefore, nanomaterials have an
  absorption effect on infrared and radar waves, so
  they can be used as coating materials for
  aircraft and submarines. Nano-coating will bring
  a new technological revolution to the coating
  technology, and will also promote the research
  and development of composite materials.

Application of nanomaterials in the development
of new energy

• The rational use of traditional energy sources
  and the development of new energy sources are
  long-term and important tasks. In recent years,
  research on the development of nano-purifiers and
  nano-combustion aids that can be used for coal
  and oil combustion, and the use of nanotechnology
  to extract useful substances in coal ash have
  obtained preliminary results and are expected to
  be industrialized. Loading precious metals on the
  surface of nano-semiconductor materials can
  double the efficiency of photodecomposing water,
  which will greatly promote the photochemical
  storage of solar energy. The photoelectric
  conversion efficiency of the new type solar cell
  made of semiconductor nanomaterials is extremely
  high, and it can work normally even in rainy days.

Conclusion

• In addition to the above applications,
  nanomaterials have good application prospects in
  the fields of printing inks, electronic pastes,
  sensors, and artificial intelligence. For
  example, the color of a nanoparticle varies
  depending on the particle size, and the smaller
  the particle size, the darker the color.
  Therefore, non-toxic nanoparticles with
  appropriate and uniform particle size can be used
  to prepare printing inks of various colors to
  replace traditional inks configured with chemical
  pigments, and this is very beneficial for
  improving the printing operation conditions,
  preventing the ink from harming the human body
  and protecting the environment.
