Here , we reporthighlyenhan c e d electrochemiluminescence (ECL) of luminol in the presence of H2O2 on indium tin oxides (ITOs) modified with both of dendrimer-encapsulated Pt nanoparticles (Pt DENs) and chemically converted graphenes (CCGs). The ITO electrodes were electrochemically modified with size-monodisperse Pt DENs via electrooxidative grafting of the terminal amines of the dendrimers encapsulating Pt nanoparticles. The Pt DENmodified ITOs were then decorated with CCG sheets via electrostatic attachments of graphene oxides (GOs) and subsequent chemical reduction of the GOs to the CCGs. The resulting CCG-Pt DEN/ITO electrodes exhibited highly catalyzed electrochemical oxidation of luminol/H2O2, leading to significantly enhanced ECL of the luminol/H2O2 system, i.e., ∼15-fold enhancement, compared to ECL emission from bare ITOs even at lower applied potentials, which allowed sensitive ECL-based analysis of H2O2 using the CCG-Pt DEN/ITOs.
