“…It is widely accepted that the liquid-phase oxidation of cyclohexane proceeds through a radical-involved autoxidation process. EPR analysis was conducted to identify ChemCatChem radical species by using 5,5-dimethyl-1-pyrroline N-oxide (DMPO) as the spin trap agent for the capture of free radicals, [30][31][32] and the electrolyte containing radicals is extracted from the electrode/electrolyte interface. The EPR spectra of seven oxidation systems are shown in Figure 4a.…”

“…PFOA is bioaccumulative, and chronic exposure to PFOA is closely linked to genotoxicity, developmental toxicity, immunotoxicity, and hepatotoxicity. The high persistence and bioaccumulating capabilities of PFASs necessitate the development of future treatment technologies in real-world implications . In this work, we propose a cathode-mediated electrochemical process for PFOA degradation with controllable SO 4 •– and HO • .…”

“…The DD value (Δ f A ) per atom A in the OTC molecule is given as the following:Δ f A = f + A − f − A = 2 q A N − 2 q A N +1 − q A N −1 where q A N is the atom A's electron population number in the OTC molecule, and f + A and f − A are obtained when the system undergoes nucleophilic and electrophilic attack, respectively. Furthermore, the OTC geometry optimization and DFT calculations of q A N , q A N +1 , and q A N −1 , were conducted in Gaussian 09 using the b3lyp/6-31 g(d) approach 39,40 combined with Multiwfn. 41,42 Table S1 in the ESI† shows the calculated DD values.…”
