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。
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.
