Composition–structure–activity relationships in CuxCo1−xFe2O4 spinel ferrites for visible-light photo-Fenton degradation of rhodamine B
Although Cu-substituted CoFe2O4 ferrites have been extensively investigated as visible-light photo-Fenton catalysts, the physicochemical basis of their composition-dependent activity maximum remains insufficiently resolved. Herein, a systematic CuxCo1−xFe2O4 series (x = 0–0.5) was synthesized within a single spinel-fer...
