ABSTRACT
The flower-shaped Pt-Au-graphene oxide ( GO ) nanostructures were synthesized by one-step electrochemical reduction method. The electrocatalytic activities of the nanostructures toward glucose oxidation were investigated by cyclic voltammetry. The results indicated that the nanocomposites exhibited a higher electrocatalytic activity than the Pt-Au nanoparticles. A glucose nonenzyme sensor could be easily developed with the use of the flower-shaped Pt-Au-GO nanostructure. The sensor exhibited low detection limit (4. 0 μmol/L), a wide and useful linear range (1. 0-25. 0 mmol/L), and high sensitivity (26. 3 μA cm-2 ( mmol)-1 ) . In addition, the sensor exhibited excellent reproducibility, stability and selectivity for the determination of glucose, and it could be used to analyze real samples.
