a Electrochemical reduction curves of CN, bCN, and IL/bCN in the CO2-bubbled system. b Electrochemical oxidation curves of CN, bCN, and Co-bCN in the N2-bubbled system. c Fitted parameter for an assumed power-law decay (ITAS∝(t-t0)−β) of bCN, Co-bCN, and IL/bCN in the gaseous mixture of N2/H2O vapor, excited by pulsed 355 nm and monitored at 900 nm. d In situ μs-TAS spectra over IL/Co-bCN in the gaseous mixture of N2/H2O vapor or CO2/H2O vapor, excited by pulsed 355 nm and monitored at 900 nm. e Electron transfer rates (ETRs) versus IL amount on IL/bCN (black circle) and IL/Co-bCN (red square). The rate constant is obtained from the slope of the linear fit, whereas the background rate is taken from the intercept. f Differential charge density diagram of the CO2 + IL/CN system with isosurface value of 0.003 e/Å3.
