Abstract

Heteroatom N and Na₂CO₃ modifications synergistically affect the PFRs formation on biochar. Pyridinic ring, with or without oxygenated groups, was the main sources of PFRs. PFRs-mediated catalytic oxidation dominated aniline degradation. SO₄^⋅− and O₂^⋅− generation significantly depends on PFRs concentration. Both O₂⋅⁻ radicals and ¹O₂ non-radicals contributed to aniline degradation.
