Valence-dependent catalytic activities of iron terpyridine complexes for pollutant degradation

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 ir...

Description
Summary: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. 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.
