Yolk–shell structured CoFe2O4 microspheres as novel catalysts for peroxymonosulfate activation for efficient degradation of butyl paraben†
Abstract
Three-dimensional yolk–shell structured CoFe2O4 microspheres were successfully prepared by hydrothermal method coupled calcination. The obtained magnetic yolk–shell microspheres exhibit excellent ability to activate peroxymonosulfate for efficient degradation of butyl paraben in wastewater followed by easy magnetic separation.
