摘要
本试验采用非均相体系反向微乳液法在室温下合成PtRu合金纳米粒子,采用X射线粉末衍射(XRD)、高分辨率透射电子显微镜(HRTEM)和X射线能量色散谱(EDS)表征PtRu合金纳米粒子的结构、形貌、尺寸和组成。TEM图片与XRD结果表明,PtRu合金纳米晶体为面心立方体结构。采用电化学测量方法,研究了PtRu合金纳米晶修饰的玻碳电极(PtRu/GCE)传感器对较高浓度的葡萄糖的检测性能。试验结果表明:在1×10^(-2) mol/L^1 mol/L范围内PtRu/GCE对葡萄糖检测具有良好的线性关系,具有良好的检测性、稳定性和重现性。
In this study, the PtRu alloy nanoparticles were synthesized by reverse microemulsion method at room temperature. The structure, morphology, size and composition of Pt Ru nanoparticles were characterized by X-ray diffraction（XRD）, high-resolution transmission electron microscopy（HRTEM） and energy dispersive X-ray spectroscopy（EDS）. Electrochemical measurement methods characterized PtRu/GCE alloy nanoparticles catalytic performance of glucose. The XRD indicated Pt Ru nanoparticles display agglomerates with face central cubic（fcc） structure. The results showed that PtRu/GEC had high determination for glucose.The results revealed that the glucose sensor had a good linear relationship in the range of 1×10^-2mol/L～（-1） mol/L for glucose, and had a good stability and reproducibility.
