Synergistic Co3O4 Nanoparticles and Nitrogen-Doped Biochar Composite for Efficient Peroxymonosulfate Activation toward Degradation of Multiple Antibiotic Pollutants

A nitrogen‑doped biochar loaded with Co3O4 nanoparticles (Co‑NBC‑550) was developed to activate Peroxymonosulfate (PMS) for antibiotic degradation in water. Tetracycline (TC, 20 mg/L) was used as a model pollutant. Under...
