Pyrolytic carbon film deposit as an electrochemical interface
Journal Title: Carbon - Science and Technology - Year 2009, Vol 2, Issue 1
Abstract
A pyrolytic carbon (PC) film was grown on planar substrate (graphite rods) by chemical vapor deposition from gaseous feed of methane using a vertical hot-wall deposition reactor. Scanning electron microscopy was used to study the surface structure. The PC film was also characterized by cyclic voltammetry technique to evaluate the background current, stability and the electrochemical response using ascorbic acid, Co(phen)32+/3+ and Fe(CN)6 3-/4- redox couples and compared to glassy carbon (GC) electrode. High degree of electrochemical activity and the enhanced signal to background (S/B) ratio demonstrated that the PC film might be an attractive electrode material for electroanalytical measurements.
