| 中文摘要: |
| 本研究采用赖氨酸（Lys）修饰的MoS2纳米片与锡酸锌复合制备n-n异质结材料，并将其沉积于纸基材料表面构建纸基NH3传感器，测试了传感器的气敏性能并探讨了气敏机理。结果表明，采用异质结构建的纸基NH3传感器在室温下对0.15 g/L NH3的响应性为11.76%，约为纸基MoS2传感器（3.34%）的3.5倍。 |
| Abstract: |
| This study utilized Lysine （Lys） modified MoS2 nanosheets and combined with zinc stannate to prepare an n-n heterojunction composite gas-sensitive material， which were then deposited onto paper-based substrates to construct paper-based NH₃ sensors. The gas-sensing performance of the sensors was tested， and the gas-sensing mechanism was investigated. The results indicated that the paper-based NH3 sensor constructed using the heterojunction exhibited a responsiveness of 11.76% to 0.15 g/L NH3 at room temperature， which was approximately 3.5 times that of the paper-based MoS2 sensor （3.34%）. |
