Fig. 8. Time courses of the generated CO (red square), H2 (blue triangle), sum of CO and H2 (black-filled square), and formic acid (green diamond) with half of the electrons flowing (dotted line) during bulk electrolysis using Re-DMF+ (0.5 mM) at –1.82 V in the DMF solution containing Et4NBF4 (0.1 M) and TPAHBF4 (25 mM) under (a) 100% and (b) 1% CO2 atmospheres (10 mL min–1). Corresponding time courses of the current during bulk electrolysis are shown in Fig. S8.† .
