Utilizing photocatalytic technology to achieve efficient production of H2O2 is a hot topic. Here, we synthesized material with strong built-in electric field, namely, Pym-CN, through hydrothermal-assisted thermal polymerization strategy, which effectively promotes the separation and transfer photoinduced charge carriers. A pyrimidine ring was successfully introduced into heptazine structure unit leads electron aggregation at N═C–N, benefiting for enhancing sorption activation capabilities oxygen. Under condition visible light wavelength greater than 400 nm (λ > nm), rate Pym-CN (2622.5 μmol/L/h) 7.6 times that BCN. detailed investigation reaction mechanism revealed follows two-step continuous process single-electron oxygen reduction (ORR). This work elucidates application prospects donor–acceptor (D–A) field in H2O2.

Ag2S/Zn2+-Decorated g-C3N4 Type-II Heterojunction with Wide-Spectrum Response: Construction and Photocatalytic Performance in Ciprofloxacin Degradation

Molecules, Journal Year: 2025, Volume and Issue: 30(7), P. 1417 - 1417

Published: March 22, 2025

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.
