Interface mechanism of catalytic ozonation in an α-Fe0.9Mn0.1OOH aqueous suspension for the removal of iohexol

[Display omitted] •1) α-Fe0.9Mn0.1OOH was synthesized by controlling Mn/Fe molar ratio of 0.1.•2)Mn can substitute Fe in α-FeOOH structure by isomorphous substitution.•3) OH played the key role in O3/ α-Fe0.9Mn0.1OOH catalytic system.•4)Oxygen vacancies on α-Fe0.9Mn0.1OOH serve as active sites for O...
