Abstract
- In this article, we report the convenient preparation of graphene/gold nanoparticle-decorating filter membrane, which could be directly used as electrode for H2O2 sensing. The graphene oxide and chloroauric acid are reduced by L-ascorbic acid before covering the paper substrate. The reduced graphene oxide/gold nanoparticle-paper material is characterized by scanning electron microscopy, X-ray diffraction and Raman spectroscopy. The paper composite could be cut into piece and directly used as electrochemical sensor. The electrochemical experimental results show that the paper sensor has satisfying performances in sensing H2O2 with the detection limit of 15 μM and the linear range is 8.53-17.35 mM. This work would propose a novel strategy for the applications of graphene in the fields of electroanalysis and sensing. [ABSTRACT FROM AUTHOR]
