| 摘要: 在本研究中，我们采用共沉淀法和退火处理合成了ZnSnO3/NiO异质结构。随后对基于上述敏感材料的传感器进行了气敏特性分析。结果表明，当Ni与Zn的物质的量之比为1∶2时，传感器性能最佳。具体来说，ZnSnO3/NiO-2基传感器在220℃下对100 μL·L-1的三乙胺气体的响应值达到70.6，是纯ZnSnO3基传感器的6.1倍。并且该传感器还具有短的响应/恢复时间(1 s/18 s)、良好的选择性、重复性以及长期稳定性。此外，对增强的气敏传感机制进行了系统地研究。 |

| 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. |
