Having successfully prepared anthraquinone-functionalised CMK-3, i.e., f-CMK-3, electrochemistry measurements were carried out in the presence of CO2 to access whether this material could capture CO2 in an electrochemically driven process. Preliminary evidence for electrochemical CO2 capture was obtained from CV experiments, where differences in the two-electrode CV profiles were observed under N2 and CO2 (Figure ). Under N2, the CV curve of the cell shows two redox events, while under CO2, the redox peaks are shifted, coalescing into a single broad peak at -1.9 V. A smaller peak at -0.75 V is also observed and has been previously linked to a stabilized quinone intermediate. Peak shifts have previously been reported in other quinone-based systems under the presence of CO2, with the second reduction peak generally reported to shift to more positive potentials while the potential of the first reduction peak remains largely unchanged. A shift in the second reduction peak to more positive potentials is caused by the reaction of the reduced quinone species with carbon dioxide. This is thought to make the second reduction more thermodynamically favorable through the stabilization of the products, leading to a shift of the second reduction peak to more positive potentials. The movement of both redox peaks that we observe for f-CMK-3 has not been previously reported in quinone-based CO2 capture chemistry. The cause for the coalescence of the two redox events is currently unknown, however, a shifting of peaks in the CV curves gave preliminary evidence for carbon dioxide capture by f-CMK-3.
