Electrochemical Exfoliation of Graphene Oxide: Unveiling Structural Properties and Electrochemical Performance

Chemistry – A European Journal, 2023
AbstractAn electrochemical exfoliation method for the production of graphene oxide and its characterization by electrochemical techniques are presented here. Graphite rods are used as working electrode in a three‐electrode electrochemical cell, and electro‐exfoliation is achieved by applying anodic polarization in a sulfuric acid solution.
