In situ EPR spectra of a DMPO-OOH and b DMPO-OH for the observation of reactive ·OOH and ·OH radicals over different photocatalysts. AH and AN were hyperfine coupling constants of hydrogen and nitrogen elements, respectively. c PL intensity of 7-HC vs. time over different photocatalysts for the quantification of ·OH. Isotopic labeled experiments d oxygen source and e carbon source for methanol production in the presence of isotopic labeled H218O, 18O2 or 13CH4.
