Summary: Tetracyclines (TCs) antibiotics are widely used in human and veterinary medicines, but their active residues released into the environment pose risks to ecosystems and human health. Photodegradation using graphitic carbon nitride (g-C3N4) as a photocatalyst provides a promising solution for complete antibiotic degradation. Doping g-C3N4 with elements improves its activity, broadens its light-responsive range, and reduces electron-hole recombination. This review discusses the design and efficiency of doped g-C3N4 for TCs degradation in aquatic environments.

Summary: Hydrothermal synthesis was used to synthesize SnCNx photocatalysts with different SnO2 content. SnCN4 photocatalyst exhibited efficient photocatalytic degradation of pollutants under visible light irradiation. The increased photoactivity can be attributed to the synergistic effect between SnO2 and g-C3N4, leading to enhanced visible light absorption. The interface interaction between the two components promotes effective charge transfer, thereby improving visible light absorption. O-2(-) and OH- were identified as the main reaction species in the degradation process, and the possible mechanism was also discussed.

Summary: A heterostructure material g-C3N4/SrZrO3 was prepared by grinding and heating a mixture of SrZrO3 and g-C3N4. The synthesized photocatalysts were characterized by various techniques, including SEM, XRD, XPS, EDS, HRTEM, and infrared spectra. The g-C3N4/SrZrO3 material exhibited visible light absorption ability and significantly higher photocatalytic activity than pristine g-C3N4 or SrZrO3. The enhanced photocatalytic performance was attributed to the efficient separation of photogenerated electrons and holes facilitated by the cooperation of g-C3N4 and SrZrO3, as demonstrated by photocurrent measurements.

Summary: Graphite carbon nitride (g-C3N4) is a promising photocatalyst with high catalytic activity, low cost, and high biosafety. However, its application in water purification is limited due to the complexity of underwater photochemical reaction conditions and the disadvantages of g-C3N4 itself. To improve its underwater photocatalytic performance, researchers prepared a g-C3N4/carbon nanotubes (CNT-CN) composite photocatalyst with high specific surface area and enhanced light absorption capacity, which showed significantly improved photodegradation efficiency under different underwater transmission light.

Summary: The construction of a sulfur doped g-C3N4/MIL-101(Fe) Z-scheme heterostructure improved the separation and migration rate of photo-induced carriers, resulting in enhanced photocatalytic activity for the degradation of methylene blue under visible light. The superior performance is attributed to the favorable band energy levels of the Z-scheme heterojunction formed between MIL-101(Fe) and g-C3N4.
