Nickel Oxide Nanopowder for Semiconductor Gas Sensor Ni2O3 Nanoparticle

Application of Nickelic Oxide Nanopowder:

With the decrease of Ni2O3 nanoparticle size, the specific surface area increases, the number of atoms on the surface increases and the surface atom coordination is caused by a large number of dangling bonds and unsaturated bonds, which makes the nanoparticles have a high surface activity, and is very sensitive to the surrounding environment, such as light intensity, temperature, atmosphere, etc., can be used to produce gas sensors. Ni2O3 is a new type of P-type semiconductor gas-sensing material. Compared with N-type semiconductor gas-sensitive materials, Ni2O3 gas sensitivity is relatively low, mainly because NiO is hole conduction, adsorption of combustible gas hole after the reduction, resistance Increase, Ni2O3 itself is also relatively high resistance. But the stability of NiO material is good, is expected to achieve a breakthrough in the combustible gas sensor.

Storage of Ni2O3 nanoparticle:

Nano Ni2O3 should be sealed and stored in a dry, cool environment, away from direct sunlight.
