Abstract:In this study, the PtRu alloy nanoparticles were synthesized by reverse microemulsion method at room temperature. The structure, morphology, size and composition of PtRu nanoparticles were characterized by X-ray diffraction(XRD), high-resolution transmission electron microscopy(HRTEM) and energy disper- sive X -ray spectroscopy (EDS). Electrochemical measurement methods characterized PtRu/GCE alloy nanoparticles catalytic performance of glucose. The XRD indicated PtRu 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 1×10-2 mol/L-1 mol/L for glucose, and had a good stability and reproducibility.
