Abstract
Recently, graphene as a material for sensors has attracted attention due to unique properties, such as: excellent electrical and thermal conductivity, chemical stability, high surface area and Young�s modulus ̴ 1GPa, very promising for electrochemical applications. Electrochemical sensors based on graphene have been used in many applications, such as: biomolecules, gases or metal ions detection. Here, we report the effect of morphology and orientation of graphene as electrode material with electrochemical method. We investigated the capacitive performance in the case of horizontal and vertical graphene sheets, synthetized by thermal chemical vapor deposition (CVD), respectively plasma enhanced chemical vapor deposition (PECVD). Graphene electrode is used in electrochemical cells with three electrodes as a working electrode. Raman spectroscopy was carried on the graphene films for quality and structure characterization. The working electrode was characterized by scanning electron microscopy (SEM), Raman spectroscopy and electrochemical method.
