Application of  Nickle Oxide Nanopowders Ni2O3 nanoparticles

1. Catalyst
Because nano-nickel oxide has a large specific surface area, among many transition metal oxide catalysts, nickel oxide has good catalytic properties, and when nano-nickel oxide is compounded with other materials, its catalytic effect can be further strengthened.

2, capacitor electrode
Inexpensive metal oxides such as NiO, Co3O4 and MnO2 can replace precious metal oxides such as RuO2 as electrode materials to manufacture supercapacitors. Among them, the preparation method of nickel oxide is simple and inexpensive, so it has attracted people's attention.

3, light absorbing material
Since nano-nickel oxide exhibits selective light absorption in the light absorption spectrum, it has its application value in the fields of optical switching, optical computing, and optical signal processing.

4, gas sensor
Since nano-nickel oxide is a semiconductor material, gas-sensitive resistance can be made by using gas adsorption to change its conductivity. Someone has developed a nano-scale composite nickel oxide film to prepare a sensor, which can monitor the toxic gas formaldehyde indoors. Some people use nickel oxide film to prepare H2 gas sensors that can be operated at room temperature.

5. The application of nano-nickel oxide in the fields of optics, electricity, magnetism, catalysis, and biology will also be further developed.
