文摘
- •
Powder and disk nickel zinc ferrite nanoparticles with diameters less than 20 nm were prepared.
- •
Sensor sensitivity of six different gases was tested in an isolated box and acetonitrile had the best sensitivity performance.
- •
The maximum sensor sensitivity was maximum at 350 °C for all tested gases except chloroform.
- •
At 200 ppm concentration, the sensor capacity is reached to the saturation state.
