Hydrogen Production and Degradation of Ciprofloxacin by Ag@TiO2-MoS2 Photocatalysts

The photocatalytic activity of silver-based catalysts containing different amounts molybdenum disulfide (MoS2; 5, 10 and 20 wt.%) was evaluated by the degradation antibiotic ciprofloxacin production hydrogen via water splitting. All silver (Ag)-based degraded more than 70% in 60 min. catalyst that exhibited best result 5%Ag@TiO2-P25-5%MoS2, with ca. 91% degradation. control experiments stability tests showed photocatalysis pathway selected were stable after seven cycles, less 2% loss efficiency per cycle 7% cycles. highest 5%Ag@TiO2 NWs-20%MoS2, 1792 μmol/hg, at a wavelength 400 nm. This amount 32 times greater obtained pristine titanium oxide nanowires catalyst. enhancement attributed to high surface area catalysts, along synergism created nanoparticles MoS2. characterized X-ray photoelectron spectroscopy (XPS), diffraction (XRD), Raman spectroscopy, field-emission scanning electron microscopy (FE-SEM), high-resolution transmission (HRTEM), Brunauer–Emmett–Teller (BET) analysis energy dispersive (EDS).
