TEMPO spin-trapping ESR spectra for the detection of electrons in DBC suspension (a). Comparison of OC signals from fresh DBC and DBC aged by SO2 under light irradiation, *C represents aromatic hydrocarbon with different functional groups (such as methyl, oxygen, and chlorine) (b). DMPO spin-trapping ESR spectra for the detection of •O2− in DBC suspension with methanol (CH3OH) under dark and light irradiation conditions (c).
