Band structure engineering in g-C3N4 by modulating nitrogen defects by B-doping and peroxymonosulfate activation for enhanced photocatalytic degradation of sulfamethoxazole

Key Points

• Enhanced photocatalytic degradation rates of sulfamethoxazole were observed with engineered g-C3N4 materials.
• Testing showed a significant increase in degradation efficiency to 85% after peroxymonosulfate activation.
• B-doping and nitrogen defects were strategically modulated to optimize the band structure of g-C3N4.
• This method may enable improved strategies for environmental remediation, though scalability needs assessment.
