A The concentration change of F− during the photodegradation of OFB. B Theoretical and detected F− concentrations after completely photodegradation of OFB (11.4 μM), FLE (50 μM) and PFOS (10 μM) with irradiation times of 2, 2 and 6 h, respectively. C Free energy change of the conversion of Si-OH into Si-F. XPS survey (D) and high-resolution Si 2p (E) and F 1s (F) of CeO2/mSiO2 before and after degradation of PFOS, taking CeO2/mSiO2 soaked in NaF solution as a reference.
