What is Nickel Oxide?
What is nickel oxide?
Nickel oxide, also known as nickelous oxide, is a common inorganic compound that is an oxide of divalent nickel with the chemical formula NiO. It comes in the form of a green powder and is used in a wide range of applications in life and in the production of high-purity (99.98% nickel) products. This product is harmful to human health and requires protection when in contact with it, and it may pose a risk of carcinogenicity and sensitization to humans.
Preparation Methods of Nickel Oxide
There are various preparation methods for nickel oxide, including solid-phase reaction, liquid-phase method, sol-gel method, microemulsion method, hydrothermal method, and so on. In the preparation process, it is necessary to control the reaction conditions, such as reaction temperature, reaction time, etc., to obtain nickel oxide powder with uniform particle size. For example, nickel oxide powder of nanometer scale can be obtained by reacting nickel sulfate with ammonium bicarbonate and then calcining at a certain temperature.Application areas of nickel oxide
Nickel oxide is a multifunctional material that has a wide range of applications in many fields. The following are some of the main application areas of nickel oxide:Catalyst:
Nano NiO is a kind of oxidation catalyst with a better catalytic effect, which plays an important role in the decomposition, synthesis, and conversion of organic matter, such as gasoline hydrocracking, and is a good catalyst in the conversion of hydrocarbons in petrochemical processing and the process of heavy oil hydrogenation.The role of nickel oxide in trans-calcite solar cells
Nickel oxide can be used as an electrode material to improve the performance of solar cells in terms of cell photoelectric conversion efficiency, stability, and service life.1) Improve the photoelectric conversion efficiency of the cell
Nickel oxide is an excellent photovoltaic material, and its light absorption ability is very strong and can convert light energy into electricity. The use of nickel oxide as electrode material in trans-calcite solar cells can improve the photoelectric conversion efficiency of the cell so that the cell can still generate electricity efficiently in the case of weak light intensity.
2) Stabilize the performance of the cell
Nickel oxide has good chemical and thermal stability. It can protect other materials in the battery from environmental pollution, oxidation, and other factors, thus improving the battery's stability and reliability.3） Extend the service life of the battery
Nickel oxide has good electrical and thermal conductivity and can effectively improve the durability and stability of the battery. Its role in the battery is to assume the function of electrode material, extending the service life of the battery and improving its reliability.Magnetic materials and ceramic glass pigments:
Nickel oxide is used in the production of magnetic materials, such as nickel-zinc ferrite. It is also used as a raw material for the manufacture of nickel salts and nickel catalysts and is applied in metallurgy and picture tubes. In addition, it can also be used as a dense adhesive and coloring agent for enamel and a pigment for ceramics and glass.Hydrogen storage material and photocatalytic degradation material:
Nickel oxide nanomaterials have unique magnetic, optical, photovoltaic, and catalytic properties, so they have broad application prospects in magnetic memory, magnetic sensors, nano-optical devices, nanoelectronic devices, and hydrogen storage materials. In addition, it is used as a photocatalyst for degrading organic dyes such as acid red.
Other fields:
Nickel oxide has also been used to improve its high-temperature stability in the preparation of reduced nickel and in the catalytic combustion of natural gas.Overall, nickel oxide is an important inorganic compound with a wide range of applications in many fields. Although it is a hazard to human health, proper precautions can ensure that we can use it safely.
