Graphitic Carbon Nitride ( g‐C 3 N 4 )‐based Sustainable Photocatalysts for Purification of Antibiotic Containing Wastewater

The unregulated and unethical discharge of pharmaceutical pollutants into aquatic sources has serious consequences, including the potential growth of antibiotic-resistant microorganisms. Conventional wastewater treatment technologies have several limitations and have been proven to be insufficient for efficient antibiotic removal. In order to deal with this alarming scenario, Semiconductor photocatalysis assisted by visible light has become a viable alternative. A brand-new hotspot nanomaterial is graphitic carbon nitride (g-C 3 N 4 ) with widely recognized as practically viable and valuable in water purification. With the aid of visible light, metal-free semiconductor photocatalysis has emerged as a competitive alternative. This chapter provides an in-depth look at recent developments in the area of antibiotic eradication using photocatalytic devices supported by g-C 3 N 4 . The chapter outlines attempts to build g-C 3 N 4 -based systems for efficient antibiotic degradation. Finally, an overview of significant improvements has also been provided.
