【摘要】 采用水热法，在30℃温度下成功合成了钯纳米颗粒(Pd NPs)/MXene的纳米复合材料，通过扫描电子显微镜(SEM)、X射线衍射仪(XRD)、透射电子显微镜(TEM)等方法对材料的结构、形貌和成分进行了表征分析，证明材料为纯Pd NPs与MXene组成，Pd NPs处于层状结构内部。将Pd NPs/MXene滴定于插指电极上制备氢气传感器用于氢气检测。结果显示，Pd NPS/MXene材料具备着良好的氢敏性能，能够在降低零点漂移、提升稳定性的同时保持良好的响应与恢复速度，延长纯Pd NPs氢气传感器60倍的使用寿命，这些提升在空气环境下的实际应用中，具有发展潜力。更多还原

【Abstract】 Hydrothermal method is used to successfully synthesize palladium nanoparticles(Pd NPs)/MXene nanocomposite at 30 ℃.The structure, morphology and composition of the material are characterized by scanning electron microscope(SEM),X-ray diffraction(XRD),transmission electron microscopy(TEM)and other methods, confirming that the material is composed of pure Pd NPs and MXene, and the Pd NPs are embeded within the layered structure.Pd NPs/MXene is titrated on an interdigitated electrode to prepare a hydrogen sensor for hydrogen detection.The results show that the Pd NPs/MXene material has good hydrogen-sensitive properties and can maintain good response and recovery speed while reducing zero-point drift and improving stability, and extending the service life of pure Pd NPs hydrogen sensors by 60 times.These improvements have potential for practical applications in air environments.更多还原
