Aromatic disulfides with extended conjugated systems: reduced reduction potential and application in electrochemical CO2 capture.

This work uses DFT calculations and CV measurements to show that aromatic disulfides with extended conjugation have more positive reduction potentials and lower energy for electrochemical CO2 capture and release (ECCR). Naphthyl disulfide (NtDS) with a larger conjugated system achieves a smaller ECCR theoretical energy consumption of 117 kJ mol-1 CO2. This work also demonstrates that aromatic disulfides are suitable for homogeneous ECCR rather than heterogeneous ECCR.
