Advanced oxidation technologies(AOPs),which based on free radical reactions,have been widely investigated as a simple,efficient and clean technology for the removal of organic pollutants.Spinel-type cobalt ferrite(CoFe2O4)is widely used as a catalyst for driving radical generation in advanced oxidation processes due to its good catalytic performance,low metal leaching rate and high recycling rate.This review takes spinel-type CoFe2O4 as the research object.Herein,the structure and properties of CoFe2O4 are outlined.The modification methods of CoFe2O4,including morphology modification,elemental doping and coupling composite materials,are summarized.The basic principles and research progress of photocatalytic oxidation of CoFe2O4 and its composites,non-homogeneous Fenton-like oxidation,peroxydisulfate oxidation and ozone-catalyzed oxidation for the degradation of organic pollutants in water are highlighted.Finally,the problems of the current study are pointed out and the direction of its subsequent research is envisioned.
