Construction of 3D electrochemically reduced graphene oxide-silver nanocomposite film and application as nonenzymatic hydrogen peroxide sensor

Herein, we provide a novel route for synthesizing electrochemically reduced graphene oxide (ERGO)-silver nanoparticle hybrid film. According to the characterization, the film should be composed of ERGO and silver nanoparticles at a 3D layer-by-layer status. Since silver nanomaterials were found to be capable of detecting hydrogen peroxide, we applied this hybrid nanomaterial for the detection of hydrogen peroxide reduction. The low-loading of silver exhibited enhanced characteristic signals. The sensor fabricated by the nanocomposite was fast, stable, and reliable to the detection of hydrogen peroxide.
