摘要

Electrochemical functionalization via electrochemical oxidation in nitric acid of various concentrations (0.1M, 0.2M and 2M) was employed to enrich the surface of carbon sphere chains (CSCs) with some useful physico-chemical properties such as hydrophilicity, oxygen functionalities and electron transfer properties. The functionalization process in 2M HNO_3 solution led to the creation of an original hybrid material made of carbon sphere chains-carbon nanobuds. This material displayed a prominent response towards the electrocatalytic oxidation of ferrocyanide with a peak current three times and twice superior to those delivered by pristine CSC and multiwalled carbon nanotubes (MWCNTs) electrodes, respectively.
