Efficient degradation of drug ibuprofen through catalytic activation of peroxymonosulfate by FeC embedded on carbon.

Ibuprofen (IBU), a nonsteroidal anti-inflammatory drug, is becoming an important member of pharmaceuticals and personal care products (PPCPs) as emerging pollutants. To degrade IBU, magnetic FeC nanoparticles embedded on N-doped carbon (FeC/NC) were prepared as a catalyst by a sol-gel combustion method. As characterized, the FeC/NC nanoparticles were composed of a NC nano-sheet and capsulated FeC particles on the sheet.

Highly efficient catalysis of chalcopyrite with surface bonded ferrous species for activation of peroxymonosulfate toward degradation of bisphenol A: A mechanism study.

Chalcopyrite nanoparticles (CuFeS NPs) with abundant surface bonded ferrous were successfully prepared, characterized and used as a catalyst for peroxymonosulfate (PMS) activation and BPA degradation. The effect of reaction parameters such as initial pH, catalyst load, PMS concentration, initial BPA concentration and reaction temperature on BPA degradation in CuFeS-PMS system was systematically investigated. As a bimetallic sulfide, CuFeS exhibits ultra-high activity for PMS activation compared with CuS, FeS, CuFeO and CoO.
