A Reliable Homemade Electrode Based on Glassy Polymeric Carbon
Abstract
The production of glassy polymeric carbon (GPC) through the thermal treatment of a phenolic resin is described. The pyrolysis process has been investigated by Fourier-transform infrared spectroscopy and powder X-ray diffraction. The final material is a conductive, nonporous, glasslike material with a rigid structure that can be used as a working electrode in electrochemical experiments. To evaluate the voltammetric performance of the electrode, the [Fe(CN) 6 ] 3- /[Fe(CN) 6 ] 4- redox couple was used. Some assays were performed to test its stability.
