▎ 摘　　要

Composite made up of silver nanoparticles and reduced graphene oxide (AgNPs-rGO) has been successfully prepared through a simple one-pot hydrothermal method using sodium borohydride as reducing agent. The structure and morphology of AgNPs-rGO have been characterized by XRD, FTIR, Raman and TEM techniques. It was observed that this composite material shows good catalytic activity for the electrochemical detection of hydrogen peroxide (H2O2). In the H2O2 concentration range of 1.0x10(-6)-1.2x 10(-3) mol/L, the electrochemical current of AgNPs-rGO/CPE increases linearly with the concentration of H2O2 (R-2 = 0.9974). The results show that the prepared AgNPs-rGO has good stability and performance reproducibility for H2O2 detection based on electrochemical analysis.
