| Abstract: | We have developed a nonenzymatic sensor for hydrogen peroxide (HP) that is based on a new kind of nanocomposite consisting of silver nanoparticles (AgNPs) electrodeposited on a basic film of a poly(ionic liquid) containing graphene. The nanocomposite was characterized by scanning electron microscopy, energy dispersive X-ray studies, cyclic voltammetry, and chronoamperometry. The AgNPs on the basic composite film provide the electrode with enhanced sensitivity in that the signal obtained for HP is 10-fold improved in the best case. The sensor exhibits good linear response in the 0.1 μM to 2.2 mM HP concentration range, and the detection limit is 0.05 μM (at S/N?=?3).  | |
