A synergistic Co 3 O 4 nanoparticles and nitrogen-doped biochar composite for efficient peroxymonosulfate activation toward degradation of multiple antibiotic pollutants

A nitrogen-doped biochar loaded with Co 3 O 4 nanoparticles (Co–NBC-550) was developed to activate peroxymonosulfate (PMS) for antibiotic degradation in water.
