Modified electrodes prepared from thiolated carbon nanostructures multi-walled carbon nanotubes (t-MWCNT) and graphene oxide (t-GO) with covalent bonded platinum (Pt) nanoparticles were used in the electrocatalytic reduction of hydrogen peroxide (H2O2). H2O2 biosensors were developed from poly(diallydimethylammonium chloride) coated t-MWCNT-Pt and t-GO-Pt on glassy carbon electrodes. They were easily and quickly prepared and showed improved sensitivity to the electrocatalytic reduction of H2O2. The Pt nanoparticles covalently bonded to the thiolated carbon nanostructures were characterized by transmission electron microscopy, X-ray photoelectron spectroscopy, and energy dispersive X-ray spectroscopy. Cyclic voltammetry and amperometry were used to characterize the biosensors’ performances. The proposed H2O2 biosensors exhibited wide linear ranges and low detection limits, giving fast responses within 10s, thus demonstrating their potential for use in H2O2 analysis.
