Overview

Electrochemical hydrogenation produces efficient hydrogen storage from graphene oxide, indicating it as a viable energy solution.

Key Points

To explore the hydrogenation of graphene oxide (GO) to create a liquid fuel for hydrogen storage in continuous flow conditions.
Utilized continuous flow electrochemical reactors to hydrogenate GO in aqueous suspension.
Examined the impact of copper and nickel foam electrolytes on hydrogen evolution and GO polarization.
Characterized the chemically hydrogenated reduced graphene oxide (rGO-H) and its thermal decomposition for hydrogen recovery.
Achieved hydrogenation at low cell potentials (1.5 V), demonstrating a scalable process.
Identified copper catalysts enhance faradaic efficiency for GO hydrogenation despite lower hydrogen gas evolution.
Demonstrated on-demand hydrogen recovery with specific binding energies of 0.98 eV/at.
