Nitrogen-Sulfur And Nitrogen-Boron Co-Doped Biochar As Peroxymonosulfate Activator For Fluoroquinolone Antibiotics Removal

Recently, the application of multi-heteroatom-doped carbocatalyst in peroxymonosulfate (PMS)-based advanced oxidation processes for removing recalcitrant pollutant has been increasingly studied. As the studies on multi-heteroatom-doped carbocatalyst in PMS activation is still nascent, the main objec...
