Facile synthesis of silver nanoparticle-decorated graphene oxide nanocomposites and their application for electrochemical sensing

Abstract

Silver nanoparticle-decorated graphene oxide (AgNPs–TWEEN–GO) was synthesized and used for fabricating a non-enzymatic H2O2 sensor. The nanocomposites were synthesized for the first time through a facile method using TWEEN 80 as the modifier for GO as well as the reducing and stabilizing agent for AgNPs. Transmission electron microscopy observations revealed that large numbers of AgNPs were distributed on the surface of the GO and the electrochemical investigations indicated that the nanocomposites possessed an excellent performance for the detection of H2O2. The linear range was estimated to be from 0.02 mM to 23.1 mM H2O2 with a low detection limit of 8.7 μM (S/N = 3) and a response time of 3 s.
