“…There is no clear oxidation of S 2 O 3 2− taking place by O 2 , which is in agreement with the previous work. 38 The pH increased from 7.1 at the start to 7.7 when the log ended (see Figure S7, Supporting Information). For O 2 concentration profile and Raman spectra profile, see Figures S8 and S9, Supporting Information.…”
