Effects of Carbon Ion on Glassy Carbon Electrode as Chemical Sensor

Abstract

Glassy polymeric carbon (GPC) is a material commonly used for making electrodes for cyclic voltammetric (CV) and amperometric measurements. Previous work done at Alabama A&M University (AAMU) has shown that high energy ion beams can be used to improve the physical properties of GPC in general. In this work, we fabricated a glassy polymeric carbon electrode and we used carbon ions to activate it. Surface analyses including Raman spectroscopy, atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS) were performed to compare the changes in surface morphology and structure before and after carbon ion bombardment.
