Photocatalytic Degradation of Tetracycline using Graphitic Carbon Nitride coupled with TiO2

Abstract

Tetracycline, an antibiotic, poses significant threats to human health and ecosystems. Wastewater treatment methods such as photocatalysis, absorption, and filtration are employed to address this issue. Titanium dioxide (TiO₂) is valued for its non-toxicity and UV light activation, while graphitic carbon nitride (g-C₃N₄) is effective for long-term pollutant degradation. Researchers enhance TiO₂'s visible light responsiveness by coupling it with g-C₃N₄, improving charge transfer and overall performance. Combining g-C₃N₄ with TiO₂ offers a promising solution for effectively removing tetracycline from wastewater.
