- •
Ethanol gas sensors based on Pd:NiFe2O4 nanoparticle thin film were fabricated.
- •
Pd incorporation in NiFe2O4 matrix inhibits grain growth.
- •
The sensors were more selective to ethanol gas.
- •
Sensors exhibited fast response and recovery when doped with palladium.
- •
Pd:NiFe2O4 thin film sensor displays excellent long–term stability.
