The development of a high-property ammonia gas sensor is of great significance for human health and environmental protection. Herein, MgFe2O4 nanomaterial was synthesized by a sol-gel method, and then a series of Ti3C2Tx-MgFe2O4 composites were prepared by an ethanol ultrasonic dispersion method. The structure and morphology of Ti3C2Tx-MgFe2O4 composites were characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The gas sensing performance of the sensors based on different ratios of Ti3C2Tx-MgFe2O4 composites was investigated. The result shows that the gas response of 2.5% (in mass) Ti3C2Tx-MgFe2O4 composite (Ra/Rg=4.7) to 100 μL/L ammonia at 25 ℃ is 3.6 times greater than that of pristine MgFe2O4 nanomaterial (Ra/Rg=1.3). Meanwhile, this composite exhibits superior selectivity and fast response/recovery durations (i.e., 10.8 s/6.6 s).

开发一种性能优异的氨气气体传感器对人类健康和环境保护具有重要意义。利用溶胶凝胶法制备了MgFe2O4纳米材料，并通过乙醇超声分散法与Ti3C2Tx复合，制备了不同比例的Ti3C2Tx-MgFe2O4复合材料。随后，采用X射线衍射、扫描电子显微镜、X射线光电子能谱分析、Fourier红外光谱等方法对Ti3C2Tx-MgFe2O4复合材料的结构和形貌进行了表征，研究了不同比例Ti3C2Tx-MgFe2O4复合材料的气敏性能。结果表明：2.5%（质量分数）Ti3C2Tx-MgFe2O4复合材料在室温（25 ℃）对100 μL/L氨气的响应（Ra/Rg=4.7）比单一MgFe2O4纳米材料（Ra/Rg=1.3）高出3.6倍，并且具有良好的气敏选择性和快速的响应/恢复时间（10.8 s/6.6 s）。

摘要
收起

开发一种性能优异的氨气气体传感器对人类健康和环境保护具有重要意义。利用溶胶凝胶法制备了MgFe2O4纳米材料，并通过乙醇超声分散法与Ti3C2Tx复合，制备了不同比例的Ti3C2Tx-MgFe2O4复合材料。随后，采用X射线衍射、扫描电子显微镜、X射线光电子能谱分析、Fourier红外光谱等方法对Ti3C2Tx-MgFe2O4复合材料的结构和形貌进行了表征，研究了不同比例Ti3C2Tx-MgFe2O4复合材料的气敏性能。结果表明：2.5%（质量分数）Ti3C2Tx-MgFe2O4复合材料在室温（25 ℃）对100 μL/L氨气的响应（Ra/Rg=4.7）比单一MgFe2O4纳米材料（Ra/Rg=1.3）高出3.6倍，并且具有良好的气敏选择性和快速的响应/恢复时间（10.8 s/6.6 s）。

The development of a high-property ammonia gas sensor is of great significance for human health and environmental protection. Herein, MgFe2O4 nanomaterial was synthesized by a sol-gel method, and then a series of Ti3C2Tx-MgFe2O4 composites were prepared by an ethanol ultrasonic dispersion method. The structure and morphology of Ti3C2Tx-MgFe2O4 composites were characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The gas sensing performance of the sensors based on different ratios of Ti3C2Tx-MgFe2O4 composites was investigated. The result shows that the gas response of 2.5% (in mass) Ti3C2Tx-MgFe2O4 composite (Ra/Rg=4.7) to 100 μL/L ammonia at 25 ℃ is 3.6 times greater than that of pristine MgFe2O4 nanomaterial (Ra/Rg=1.3). Meanwhile, this composite exhibits superior selectivity and fast response/recovery durations (i.e., 10.8 s/6.6 s).
