Preparation of reduced graphene oxide decorated with high density Ag nanorods for non-enzymatic hydrogen peroxide detection

Abstract

Reduced graphene oxide (rGO) decorated with high density Ag nanorods has been prepared by reduction of GO and AgNO3 using ethylene glycol as reducing agent and solvent. The resulting hybrids exhibit good performance for the non-enzymatic detection of hydrogen peroxide, with a linear detection range of 0.1 to 70 mM (r = 0.9996), and a detection limit of 2.04 μM at a signal-to-noise ratio of 3.
