Infrared light-assisted preparation of Ag nanoparticles-reduced graphene oxide nanocomposites for non-enzymatic H2O2 sensing
A green method has been developed for preparation of Ag nanoparticles/reduced graphene oxide (AgNPs/rGO) nanocomposites by infrared light irradiation. The characterizations indicate the successful preparation of AgNPs/rGO nanocomposites. Most importantly, AgNPs/rGO nanocomposites exhibit excellent electrocatalytic activity for reduction of H2O2, leading to a high-performance non-enzymatic H2O2 sensor with linear detection range and detection limit about 0.1 mM to 140 mM (r=0.9896) and 3.0 mu M, respectively.
