Mechanistic insights into the naphthalene degradation by biochar-supported nZVI activated persulfate

Key Points

• Naphthalene degradation increased significantly with biochar-supported nZVI, improving pollutant removal efficiency.
• Key evidence shows that degradation rates were accelerated by over 50% in optimized conditions.
• Analysis of biochar-supported systems demonstrated strong catalytic activity using activated persulfate for degradation.
• These findings highlight new methods for soil and water pollution remediation with biochar-based catalysts.
