Gas Sensing Element of a Conductometric Nitrogen Dioxide Sensor Based on Oriented Nickel Oxide Networks

The creation of sensors capable of detecting nitrogen dioxide molecules in the atmosphere is one of the most important tasks since this gas is a highly toxic oxidizing gas that has a negative impact on the environment and the human body. To solve this problem, this paper proposes to develop a gas-sensitive element based on oriented networks of nickel oxide. An oriented nickel oxide network is obtained on the surface of a silicon substrate with conductive electrodes. Microscopic studies of the resulting mesh were carried out, and the elemental composition and thermal properties were also studied.
