Published: Oct. 29, 2024

China is a significant global producer and consumer of pesticides antibiotics, with their excessive use leading to substantial water pollution that poses challenges for subsequent treatment. Photocatalytic degradation, leveraging renewable solar energy, presents an effective approach decomposing organic pollutants reducing residual contaminant levels in bodies. This represents one way addressing environmental challenges. paper classifies representative photocatalytic materials by structural design degradation principles including MOFs (Metal–Organic Frameworks), metal- nonmetal-doped, mesoporous material-loaded, carbon quantum dot-modified, floatation-based, heterojunction photocatalysts. We also discuss research on pathways reaction mechanisms antibiotics. Of particular importance are several key factors influencing efficiency, which summarized within this work. These include the separation charge transfer rate catalyst surface carriers, wide-spectrum response capabilities photocatalysts, as well persulfate activation efficiency. Furthermore, emphasis placed role played intrinsic driving forces such built-in electric fields catalytic systems. Moreover, introduces promising composite-structure technologies from both perspectives (e.g., Aerogel-based composites) composite-method molecularly imprinted synthesis method). latest development status, along future prospects, presenting valuable insights pollutant targets. work aims facilitate efficient materials, while providing theoretical references governance technologies.

Tunable Metal-Free COFs for Photocatalytic Degradation of Water Pollutants

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: April 26, 2025

Photocatalytic degradation is an effective method for removing organic pollutants from water; however, metal-based photocatalysts may lead to secondary pollution. Covalent frameworks (COFs), owing their inherent stability and porosity, have emerged as promising candidates photocatalysis. In this study, we report a metal-free photocatalyst, Acetylenyl-TPB-DMTP-COF, which efficiently degrades dyes under both UV visible light, without requiring metal doping or sacrificial agents. The pristine COF achieves over 95% efficiency maintains more than 90% of its activity after five cycles, demonstrating excellent stability. Furthermore, functionalization via click chemistry allows the introduction hydroxyl groups, significantly enhancing ability degrade sulfonamide antibiotics, with removal up 58.9%. Notably, material functions entirely components additives, offering environmentally friendly solution water treatment. These results highlight potential COFs efficient sustainable purification.

The present study outlines the synthesis of cadmium sulfide-metal–organic framework (CdS-MOF) MIL-101 (Fe) heterojunctions achieved via fast microwave-assisted reactions. Thus, different CdS-MOF ratios were prepared to their effectiveness as photocatalysts. These compounds employed in photocatalytic degradation methylene blue (MB) under UV and visible irradiation. Structural, morphological, textural, compositional, optical properties synthesized determined by X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), UV–vis spectroscopy, Raman Fourier transform infrared (FTIR) utilized characterize structural, properties. Electrochemical impedance (EIS) was also determine photovoltage photocurrent densities. resulting valence band offset (Vfb) gap energy values construct an scheme. Our research revealed that heterojunction enhances efficiency electron–hole pair separation, thereby mitigating charge carrier recombination effects. Moreover, type I electronic structure established efficient reaction mechanism, effectively suppressing photogenerated pairs. system demonstrated exceptional behavior, achieving complete MB removal within 30 min time exhibiting outstanding stability reusability after four cycles. findings highlight potential field wastewater treatment for organic pollutants, offering a promising alternative current environmental issues.

Materials, Journal Year: 2024, Volume and Issue: 17(24), P. 6225 - 6225

Published: Dec. 20, 2024

The rational design of heterojunction photocatalysts enabling fast transportation and efficient separation photoexcited charge carriers is the key element in visible light-driven photocatalyst systems. Herein, we develop a unique Z-scheme consisting NiMoO4 microflowers (NMOF) ZIF67, referred to as ZINM (composite), for purpose antibiotic degradation. ZIF67 was produced by solution process, whereas NMOF synthesized via coprecipitation with glycine surfactant. exhibited monoclinic phase highly oriented, interconnected sheet-like morphology. showed better optical transfer characteristics than its constituents, NiMoO4. Consequently, developed superior photocatalytic redox capability; ZINM30 (the composite 30 wt.% loaded) could degrade 91.67% tetracycline 86.23% norfloxacin within 120 min. This enhanced activity attributable reduced bandgap (Egap = 2.01 eV), morphology, high specific surface area (1099.89 m2/g), intimate contact between NiMoO4, which facilitated establishment heterojunction. Active species trapping tests verified that •O2− h+ were primary species, supporting proposed degradation mechanism. work highlights valid ZIF67/NiMoO4 system carrier and, therefore, antibiotics.
