Construction of 1D/2D α-Fe2O3/SnO2 Hybrid Nanoarrays for Sub-ppm Acetone Detection

Figure 6

Reproducibility of (a) SnO2 NSAs, (b) α-Fe2O3 NRs, and (c) α-Fe2O3/SnO2 HNA-based sensors toward acetone (5 ppm and 1 ppm, each of 5 cycles) at 340°C; (d) is the corresponding comparison of the sensor responses. (e) Stability of α-Fe2O3/SnO2 HNA-based sensor toward 5 ppm acetone at 340°C for 93 days; the inset is the SEM image of α-Fe2O3/SnO2 HNAs taken after 93 days of gas sensing test. (f) Response of α-Fe2O3/SnO2 HNA-based sensor to 5 ppm acetone at 340°C under different relative humidity (20–90% RH).
