Structural and compositional tuning in g-C3N4 based systems for photocatalytic antibiotic degradation

The uncontrolled and unethical release of pharmaceutical contaminants into aquatic sources have severe adversities, including the possible emergence of antimicrobial-resistant bacteria. Photocatalysis utilizing semiconductor heterostructures is a greener and sustainable option for the effective degr...
