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.

Abstract An innovative palladium‐doped zinc cobalt oxide nanoelectrocatalyst, ZnPd x Co 2‐x O 4 (0.00 ≤ 0.08)@NF, is successfully synthesized using a hydrothermal method. The resulting material exhibits spinel phase, as confirmed by X‐ray diffraction (XRD). electrocatalytic performance of 0.08)@NF evaluated for the hydrogen evolution reaction (HER). results show significant improvements in efficient production, with an overpotential 31 mV, Tafel slope 54.36 mV dec⁻ 1 , and sustained stability over 72 h, chronopotentiometry methods. Doping 8.0% Pd concentration enhances highest electrochemical supporting idea that doping improves HER activity. suggest increased active surface area (ECSA) faster charge transfer kinetics at interface between semiconductor electrolyte contribute to enhanced performance. DFT calculations performed this work confirm role improving catalytic activity ZnCo 2 catalyst. Overall, study has made contribution development sustainable energy solutions, offering promising path toward production fuel.
