摘要

采用水热法合成了SnO2/MXene复合材料，SnO2纳米片均匀生长在MXene薄片表面。与纯SnO2相比，5% MXene-SnO2传感器在较低的工作温度(160℃)下表现出最佳的甲醛传感性能。此外，在1 ~ 100 ppm的浓度范围内，含有5% MXene-SnO2的传感器也表现出高响应、良好的选择性、良好的重现性和良好的线性。

Enhanced Formaldehyde Sensing Performance Based on SnO2 Nanosheets/Titanium Carbide (MXene) Composites

SnO2/MXene composites were synthesized by a facile hydrothermal method, where the SnO2 nanosheets grew evenly on the surface of MXene flakes. Compared with the pure SnO2, the 5% MXene-SnO2 based sensor displayed optimal formaldehyde sensing performance at a lower operating temperature of 160 °C. Furthermore, the sensor with 5% MXene-SnO2 also showed high response, good selectivity, excellent reproducibility, and a good linearity over the concentration of 1–100 ppm.
