Purification of water using TiO2/g-C3N5 nanocomposite: a visible light assisted photocatalytic activity.

Tetracycline hydrochloride (TCN), widely recognized for its broad-spectrum efficacy and cost-effectiveness as an antibiotic, has raised significant environmental and health concerns due to its contamination in water bodies. This study introduces an innovative approach to address this issue by employing a titanium dioxide/graphitic carbon nitride (TiO₂/g-C₃N₅) nanocomposite through photocatalysis. The synthesis of this composite involved a hydrothermal method, and a comprehensive characterization was conducted using XRD, FT-IR, and SEM techniques. The formed heterojunction between TiO₂ and g-C₃N₅ exhibited remarkable photocatalytic degradation capabilities, achieving a removal rate of over 85 % within a short period of 135 min. This signifies the composite's efficiency in breaking down TCN in aqueous environments. Beyond its high effectiveness, the TiO₂/g-C₃N₅ nanocomposite presents itself as an environmentally friendly and sustainable solution for addressing the critical issues associated with antibiotic contamination in water. This study underscores the potential of photocatalysis using TiO₂/g-C₃N₅ as a promising technology for mitigating the adverse effects of TCN on both ecosystems and human health. [ABSTRACT FROM AUTHOR]
