Antibiotic-based wastewaters seriously endanger human health and damage the ecological environment, photocatalytic degradation is a desirable strategy for eliminating these contaminants in water. Therefore, developing proper catalyst photodegradation of antibiotics, including ciprofloxacin (CIP), great importance. In this study, novel Ag2S/Zn2+-decorated graphitic carbon nitride (AZCN short) type-II heterojunctions are constructed through precipitation–calcination procedure. The high porosity with specific surface area 133.5 m2 g−1, as well positive synergy between Ag2S- Zn2+-decorated (abbreviated ZCN), enhance incident light harvesting, increase adsorption capacity reactant molecules, favor mass transfer promote separation transport photoinduced carriers, therefore improving efficiency CIP. Specifically, CIP (50 mL, 10 mg L−1) over 2.5% AZCN (10 mg) 18.1%, 43.1% 55.7% within 60 min irradiation using near-infrared light, visible simulated solar respectively. Moreover, it displays satisfactory recycling stability excellent universality. This research not only develops promising heterojunction photocatalyst but also offers some valuable insights water remediation.

Bismuth vanadate (BiVO4), a well-known semiconductor photocatalyst with various advantages, has shown great potential in addressing energy and environmental issues. However, its inherent drawbacks restrict the photocatalytic performance of pure BiVO4. In past few years, many efforts have been devoted to improving catalytic activity BiVO4 revealing degradation mechanism depth. this review, we summarized recent progress on field degradation, including strategies which enhance light absorption ability suppress recombination charge carriers BiVO4, as well related mechanism. Finally, future prospects challenges are summarized, may provide new guidelines for designing more effective BiVO4-based photocatalysts persistent organic pollutants.

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.
