The S-Scheme heterojunction design offers a promising pathway to enhance the photocatalytic activity of semiconductors for antibiotic degradation in aquatic environments. Graphitic carbon nitride (g-C3N4) stands out due its robust visible light absorption, exceptional charge separation efficiency, and abundant active sites, rendering it an ideal candidate sustainable energy-efficient photocatalysis. This review delves into potential g-C3N4-based heterojunctions degradation, with particular emphasis on principles, inherent advantages, application prospects. We discuss various semiconductor materials, including metal oxides, multicomponent magnetic sulfides, which can be paired g-C3N4 fabricate heterojunctions. Furthermore, we explore common preparation techniques synthesizing composites, such as hydrothermal method, solvothermal calcination self-assembly situ growth, etc. Additionally, summarize applications these antibiotics, focusing specifically quinolones tetracyclines. By providing insights development heterojunctions, actively contribute ongoing exploration innovative technologies field degradation. Our findings underscore vast addressing challenge contamination water sources.
