Effective Combination of MOF and MoS2 Layers: A Novel Composite Material Capable of Rapidly Degrading Dyes

Water, Journal Year: 2025, Volume and Issue: 17(7), P. 980 - 980

Published: March 27, 2025

This study successfully prepared MIL-101(Fe)@MoS2 composite photocatalysts via hydrothermal methods to address the efficient removal of refractory organic dyes in dye wastewater. Characterization using X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS) confirmed that molybdenum disulfide (MoS2) was uniformly loaded onto surface MIL-101(Fe), forming a heterojunction significantly enhanced light absorption capacity charge separation efficiency. In visible-light-driven photo-Fenton system, this material exhibited excellent degradation performance for Congo red (CR). At an initial CR concentration 50 mg/L, catalyst dosage 0.2 g/L, 4 mL added H2O2, pH 7, completely degraded within 30 min, with total carbon (TOC) reaching 72.5%. The maintained high efficiency (>90%) across range 3–9, overcoming traditional Fenton system’s dependency on acidic media. Radical-trapping experiments indicated superoxide radicals (·O2−) photogenerated holes (·h+) were primary active species responsible degradation, revealing synergistic catalytic mechanism at interface. Recyclability tests showed retained 90.8% after five cycles, photoelectron (XPS) analysis demonstrated stable binding Fe Mo, preventing secondary pollution. provides scientific basis developing efficient, stable, wide-pH adaptable systems, contributing advancement green water treatment technologies.

Efficient Degradation of Ciprofloxacin via Peroxymonosulfate Activation over a Hierarchically Porous Cu–Ti Alloy Manufactured by 3D Printing

ACS ES&T Water, Journal Year: 2024, Volume and Issue: unknown

Published: July 2, 2024

3D printed alloy catalysts have garnered significant attention in water purification due to their high efficiency, adaptable structure, and easy recovery. Here, a straightforward cost-effective three-dimensional (3D) printing strategy is adopted synthesize copper–titanium (Cu–Ti) for ciprofloxacin (CIP) degradation through peroxymonosulfate (PMS) activation. The resulting Cu–Ti alloy, characterized by hierarchical porous exhibits the highest removal efficiency of 90.55% CIP degradation, surpassing that commercial Cu Ti powders under similar conditions. Capture experiments electron paramagnetic resonance measurements reveal involvement •OH, 1O2, SO4•–, O2•– CIP, with •OH 1O2 playing dominant roles. presence not only promotes Cu(I)/Cu(0) Cu(II)/Cu(I) cycling but also facilitates activation dissolved oxygen water, thereby reducing its reaction PMS preventing corrosion, ultimately rendering 3D–Cu-Ti/PMS excellent catalytic activity reusability. Additionally, bean sprout growth indicate remarkable reduction toxicity products. utilization technology construction offers promising
