Electrocatalytic reduction of H{sub 2}O{sub 2} by Pt nanoparticles covalently bonded to thiolated carbon nanostructures

Abstract

Highlights: Black-Right-Pointing-Pointer Novel thiolated carbon nanostructures - platinum nanoparticles [t-GO-C(O)-pt and t-MWCNT-C(O)-S-pt] have been synthesized, and [t-GO-C(O)-pt and t-MWCNT-C(O)-S-pt] denotes as t-GO-pt and t-MWCNT-Pt in manuscript, respectively. Black-Right-Pointing-Pointer The modified electrode denoted as PDDA/t-GO-pt/GCE was used for the electrochemical determination of H{sub 2}O{sub 2} for the first time. Black-Right-Pointing-Pointer The results show that PDDA/t-GO-pt nanoparticles have the promising potential as the basic unit of the electrochemical biosensors for the detection of H{sub 2}O{sub 2}. Black-Right-Pointing-Pointer The proposed H{sub 2}O{sub 2} biosensors exhibited wide linear ranges and low detection limits, giving fast responses within 10 s. - Abstract: Glassy carbon electrodes were coated with thiolated carbon nanostructures - multi-walled carbon nanotubes and graphene oxide. The subsequent covalent addition of platinum nanoparticles and coating with poly(diallydimethylammonium chloride) resulted in biosensors that detected hydrogen peroxide through its electrocatalytic reduction. The sensors were easily and quickly prepared and showed improved sensitivity to the electrocatalytic reduction of H{sub 2}O{sub 2}. 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 sensors exhibited wide linear ranges and low detection limits,  More>>
