This work deals with the modification of the surface of carbon black (CN) N330 to increase its catalytic properties and to study the possibility of using it as an electrochemical sensor in the detection of analytes such as hydrogen peroxide by its reduction reaction.
This improvement of the catalytic activity has been carried out by plasma treatment modification in the nitrogen/hydrogen atmosphere to achieve nitrogen immobilization on the NC surface. In a subsequent step, the carbon structure has been doped with iron by creating a Fe-phenanthroline complex through pyrolysis in a 0.5% Argon- hydrogen atmosphere.
In the present work, the relationship between the surface modification of the NC and its catalytic properties has been established by using electrochemical techniques, such as cyclic voltammetry, linear sweep voltammetry, and chronoamperometry, and surface characterization techniques such as thermogravimetric analysis and X-ray photoelectron spectroscopy.
