Sensors based on porous Pd-doped hematite (α-Fe2O3) for LPG detection

- Pd-doped hematite NPs sensors were prepared by coprecipitation for LPG detection.
- Doped samples showed much higher response to LPG than the undoped counterpart.
- Developed sensors allowed detecting LPG from 150 to 8000 ppm, with good performance.
