A Vehicle-Mounted Sensor for Real-Time Alcohol Content Monitoring Based on La<sub>2</sub>O<sub>3</sub>/LaFeO<sub>3</sub> Composite Materials
Alcohol sensors for vehicles are currently one of the key research areas in the automotive industry. In this work, La 2 O 3 /LaFeO 3 composite materials were successfully prepared using citric acid complexation method.The samples obtained were characterized by XRD, XPS, and SEM, and their gas-sensitive properties were tested using professional methods. Finally, the morphology and gas-sensitive properties of the materials with and without the addition of SDS were compared. The results showed that the structured material exhibited high sensitivity to ethanol gas, good concentration linear response signals, and excellent stability, making it a promising key material for a new generation of on-board alcohol gas sensors.
