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.
