The possibility of following electrochemical processes in situ and in real time using optical techniques is important in view of shining a light on the chemical processes at the surface.

Here, we show how graphite anion intercalation–an important chemical process to massively produce graphene flakes–can be monitored by a UV-vis spectrometer when the graphite works as an electrode immersed inside the electrochemical cell.

Abstract

The possibility of following electrochemical processes in situ and in real time using optical techniques is important in view of shining a light on the chemical processes at the surface. The interest grows if the optical apparatus is compact and can be employed in industrial quality-check protocols. Here, we show how graphite anion intercalation–an important chemical process to massively produce graphene flakes–can be monitored by a UV-vis spectrometer when the graphite works as an electrode immersed inside the electrochemical cell. Important information on the reversibility or quasi-reversibility of the reaction shows a clear visualization in optical color maps.
