Abstract

Herein, iron–terpyridine complexes with the iron centers at different initial valence states were utilized as homogeneous catalysts for the degradation of phenol in water. The iron(III)–terpyridine complex induced the formation of more high-valent iron–oxo centers and hydroxyl radicals than the iron(II)–terpyridine complex, leading to a higher catalytic activity.
