Appendix A.I. Wet experiments with Ni electrode in MeCN-MM electrolyte CO2 reduction experiments were conducted with 0.5 mol% of MM NTf2 in acetonitrile under wet conditions– using a Ni wire electrode. Post-electrolysis NMR analysis revealed the presence of ethanol as one of the products (Figure A.I.1-2). To contrast the results obtained under wet conditions, CO2 reduction experiments were also performed with 0.5 mol% of MM NTf2 in acetonitrile under dry conditions. Post-electrolysis NMR analysis did not identify the presence of water and ethanol, and only CO was detected as the product (Figure A.I.3-4).
