Correction to “Catalyst-Free Radical Reaction Driven by Interfacial Electric Fields in Organic Microdroplets under Ambient Conditions”

In Figure 4c of the original manuscript, the electron paramagnetic resonance (EPR) signal was incorrectly assigned as DMPO-OH. The correct assignment should be DMPO oxide (DMPOX). Therefore, the discussion regarding Figure 4c which purports to prove the generation of hydroxyl radicals is incorrect. The corrected Figure 4c and related discussion are shown below. Prior to atomization, only baseline signals were observed. Following 30 min of reaction under Ar, characteristic signals of H• were detected. Notably, under an air atmosphere, signals of DMPO oxide (DMPOX) were detected, indicating the presence of reactive species that oxidize DMPO to DMPOX. We seculate that this is due to the reaction of H• with O2 to form hydroperoxyl radicals (•OOH), and the subsequent decomposition of •OOH generates oxygen-active species.
