ABSTRACT
The gas sensors have been widely used in various fields, to protect the safety of life and property. A novel heterostructure of Fe-O-Ti nanoparticles is fabricated by hydrothermal and wet chemical deposition methods. The Fe-O-Ti nanoparticles with a large number of pores possess high surface area, which is in favour of high-performance gas sensors. Compared with pure Fe2O3 and TiO2, the Fe-O-Ti composite exhibits obviously enhanced sensing characteristics, such as faster response-recovery time (T res = 6 s, T rec = 48 s), higher sensing response (response = 35.6) and better selectivity. The results show that the special morphology and large specific surface area of mulberry-like Fe-O-Ti heterostructures provided a large contact area for gas reactions.
