a FTIR spectra for adsorption of gaseous mixture of CO2/H2O vapor on IL/bCN (left panel) and Co-bCN (right panel) in dark, respectively. b In situ FTIR spectra for the CO2 photoreduction process on IL/Co-bCN. c Illustration of the proposed photocatalytic mechanism of CO2 photoconversion over IL/Co-bCN under UV–vis light irradiation.
