Graphene–polydopmine–Pt nanoparticles hybrid nanomaterial for electrocatalytic glucose oxidation

A novel electrocatalytic nanomaterial was prepared by anchoring Pt nanoparticles on polydopamine reduced graphene and its electrocatalytic activity for glucose oxidation is evaluated at different conditions. Pt@rGo modified glass carbon electrode are characterized with different techniques like (FE-SEM) high resolution transmission electron micrograph (TEM) and The electrocatalytic oxidation of glucose at Pt@-rGO electrode is significantly improved especially with Pt@-rGO is believed to play a crucial role as a catalytic mediator to facilitate the charge transfer during the oxidation of glucose.
