Graphitic C3N4 as a powerful catalyst for all-vanadium redox flow batteries

摘要

A novel carbon felt electrode modified with carbon nitride (C3N4) was developed to improve the electrochemical performance with a VO2+/VO2+ redox pair. The graphitic C3N4 on carbon felt exhibited an excellent performance in an all-vanadium redox flow battery. This work, for the first time, demonstrates the electrocatalytic properties of C3N4 for use in VRFBs.
