Magnetic recyclable g-C3N4/Fe3O4@MIL-100(Fe) ternary catalyst for photo-Fenton degradation of ciprofloxacin

Hematite nanoparticle decorated MIL-100 for the highly selective and sensitive electrochemical detection of trace-level paraquat in milk and honey

“…The peak at 1574 cm − 1 may be caused by the C--C stretching in benzene [43]. The absorption band at 1628 cm − 1 is caused by the asymmetric vibration of C-O [44]. The characteristic peak at 3450 cm − 1 is related to OH stretching vibration in water [45].…”

The influence of ferrocene anchoring method on the reactivity and stability of SBA-15-based catalysts in the degradation of ciprofloxacin via photo-Fenton process

“…Moreover, it exhibited comparable reactivity to that established for C 3 N 4 /Fe 3 O 4 /MIL-100(Fe) ternary heterojunction ( k = 0.0656 min −1 ). 49 However, reactivity of Fc/Cl/SBA-15 was found to be lower than that reported previously for rGO–ZnFe 2 O 4 ( k = 0.095 min −1 ) by Yang et al 50…”

Reaction conditions: in a given catalytic test evaluating reactivity of the leached ferrocene species, 30 mg of Fc-containing catalyst was stirred to CIP solution (80 mL, 15 mg L −1 , pH = 3) and agitated in the dark for 1 h (stirring rate: 600 rpm).…”

Fe3O4@MIL-100(Fe) modified ZnS nanoparticles with enhanced sonocatalytic degradation of tetracycline antibiotic in water

“…The XRD diffraction peaks of FM are located at 10.8, 14.2, 18.5, 19.8, 24.0 and 27.8° corresponding respectively to the (4 2 8), (0 8 8), (7911), (4814), (6618) and (9321) crystal planes of MIL-100(Fe). Fe3O4 has weak diffraction peaks due to its low content [23] . The diffraction peaks of FM/ZnS hybrid material are highly consistent with that of ZnS.…”

“…This peak is significant in the composite FM/ZnS as the specific gravity of FM increases. Due to the extremely low content of Fe 3 O 4 , it is difficult to locate the Fe–O bond [23] . In summary, FM and ZnS have formed a stable chemical bond structure.…”
