Towards the Mechanism of Protonic Transport in Graphene Oxide
Abstract
Graphene oxide (GO) has been considered as a good ionic conductor and an electronic insulator simultaneously. The mechanism of the protonic conductivity in GO has not been studied carefully yet. This report presents new experimental data of the protonic conduction in GO in a wide temperature range with the humidity as a parameter. The activation energy of the protonic transport (approx. 0.7 eV) was obtained from the Arrhenius plots. Applications of GO membranes to the humidity sensors and to solid-state electrolyte energy storage devices have been considered.
