摘要

In this work, PdAu nanoflowers was synthesized and used to fabricate hydrogen peroxide sensor. Thesensor was fabricated by simple dropping of the mixed solution of chitosan and PdAu nanoflowers ona glassy carbon electrode. Using electrochemical impedance spectroscopy and cyclic voltammetry, wecharacterized the modified electrode. The proposed sensor exhibited a good performance due to theexcellent electrocatalytic activity of PdAu nanoflowers toward H 2 O 2 in a wide linear range from 0.05to 12 mM with a low detection limit of 1.5 μM (S/N=3). Moreover, the proposed sensor exhibitedsatisfying reproducibility and stability. The practical application of the nonenzymatic sensor wasinvestigated via determination of H 2 O 2 in real disinfected fetal bovine serum samples.
