Abstract

Graphene oxide (GO) can be conveniently used as a starting material for the preparation of selective and sensitive electrochemical sensing systems. The amount of oxygen groups present on the material can be precisely tuned by reduction methodologies which allow the selection of the optimal C/O ratio for specific analytes. An electrochemical reduction procedure is used in this work to alter the oxygen content of the GO starting material and investigate the effects on the electrochemical detection of phenolic compounds selected with different hydroxyl groups: phenol, catechol, hydroquinone and phloroglucinol. Cyclic voltammetry has been used to measure the alteration of the oxidation signal upon tuning the oxygen content of the graphene based electrode material.
