“…OH. In addition, complex compounds of phosphate-Co could be produced in the presence of phosphate ions [44]. It was reported that the active sites such as surface hydroxyl groups will be occupied by phosphate and undermine the inner-sphere complexation due to their very strong affinity to active sites [15,49].…”

h i g h l i g h t sCo-OMC catalyst possesses high specific surface area and uniform pore size. /g) and uniform pore size distribution ($4 nm) because of its ordered mesoporous structure. 20 mg/L phenol could be completely degraded with the addition of 0.1 g/L Co-OMC and 1 mM PMS in 60 min. In addition, the catalytic activity of Co-OMC for PMS activation was much higher than some efficient catalysts such as Co 3 O 4 , CoFe 2 O 4 and OMC. Besides, Co-OMC showed remarkable efficiency for the destruction of seven representative pollutants. Results indicated that the catalytic activity of Co-OMC increased with the calcination temperature increasing, which may be caused by the higher defect degree at higher calcination temperature. In addition, various practical parameters such as PMS concentration, initial pH, anion, nature organic matter and reaction temperature were systematically investigated using phenol as the target pollutant.

“…In last decade, the application of peroxymonosulfate (PMS) in degradation of environmental pollutants has received great attention. PMS is an asymmetrical oxidant which is activated by transition metals, UV irradiation, ultrasound, heat, and carbon-based catalyst [17,18]. PMS can generate sulfate and hydroxyl radicals through activation by conduction electron i.e.…”

Sulfate radical (SO 4 c À ) based advanced oxidation processes allow efficient degradation of refractory organics, but efficient, low-cost, and robust catalysts for such processes are still lacking. In this work, a magnetically recoverable heterogeneous catalyst was fabricated by immobilizing spinel cobalt-ferrite (CoFe 2 O 4 ) particles on graphitic carbon nitride nanosheets (CNS) using a low-cost, one-step solvothermal method. In the CoFe 2 O 4 -CNS nanocomposite, the CoFe 2 O 4 particles were evenlydistributed on the CNS surface, giving the nanocomposite a high specific surface area and significantly raised activity for peroxymonosulfate (PMS) activation and sulfonamide degradation compared to the bare CoFe 2 O 4 NPs, which were considerably aggregated. In addition, the CoFe 2 O 4 -CNS could be more efficiently separated under magnetic field and resuspended compared with the bare CoFe 2 O 4 due its larger sizes and no agglomeration. A stable activity of the nanocomposite catalyst during repeated use was also demonstrated. Our results imply high potential of CoFe 2 O 4 -CNS for sustainable water treatment and environmental remediation applications.
