| Abstract: In this study, ZnSnO3/NiO heterostructures were synthesized using a co-precipitation method followed by an annealing process. The gas-sensitive characteristics of the sensors based on these samples were evaluated. The results indicate that the sensor performance was optimized when the molar ratio of Ni to Zn was 1∶2. Specifically, the response values of the ZnSnO3/NiO-2-based sensor to 100 μL·L-1 triethylamine (TEA) gas at 220 ℃ reached 70.6, which were 6.1 times higher than that of the pure ZnSnO3 based sensor. The findings demonstrate that ZnSnO3/ NiO heterostructures exhibited not only short response and recovery times (1 s/18 s) but also good gas selectivity, repeatability, and long-term stability. The enhanced sensing mechanism has been investigated in detail. |
