Research progress of peroxymonosulfate activated by solid-phase cobalt-based catalyst in water treatment

Advanced oxidation technology using peroxymonosulfate driven by solid-phase cobalt-based catalysts has received extensive attention from researchers in recent years due to its high catalytic activity and easy separation from water. This article reviewed the research progress of the solid-phase cobalt-based catalysts for peroxymonosulfate activation in recent years, and summarized the types of the cobalt-based catalysts and their modification methods. The applications of advanced oxidation technology with cobalt-based persulfate in the reduction of refractory organic pollutants were introduced, and the effects of various water quality environmental factors on the reduction efficiency were analyzed. Further, the oxidation mechanism of the cobalt-based catalyst activated peroxymonosulfate was explained. Finally, the future development of solid-phase cobalt-based catalysts is expected to move towards large-scale, low leakage, high circulation, low energy consumption, having magnetic effects, or integration with membrane reactors.
