“…However, these materials suffered from some insufficiencies: (1) LDHs and clays exhibit slow sorption kinetics and limited selectivity; (2) ACs and carbonaceous materials possess disadvantages of small pore volumes or pore sizes; (3) GO and CNTs are complicated to synthesize and produce; (4) the poor regeneration and reusability of organic resins; and (5) relatively low chemical and thermal stability of LMS. 147 Novel nanomaterials, such as polymer adsorbents, 148 2D MXenes, 149 , 150 , 151 , 152 , 153 nanoscale zero-valent iron (NZVI), 154 , 155 , 156 , 157 , 158 , 159 g-C 3 N 4 , 120 , 160 , 161 , 162 , 163 , 164 MOFs, 165 , 166 , 167 , 168 and COFs, 169 , 170 , 171 are constantly applied to improve their applications in environmental pollution cleanup owing to their superior performance. MOFs and COFs represent porous crystalline materials for network topology.…”

Summary Covalent organic frameworks (COFs) are a new type of crystalline porous polymers known for chemical stability, excellent structural regularity, robust framework, and inherent porosity, making them promising materials for capturing various types of pollutants from aqueous solutions. This review thoroughly presents the recent progress and advances of COFs and COF-based materials as superior adsorbents for the efficient removal of toxic heavy metal ions, radionuclides, and organic pollutants. Information about the interaction mechanisms between various pollutants and COF-based materials are summarized from the macroscopic and microscopic standpoints, including batch experiments, theoretical calculations, and advanced spectroscopy analysis. The adsorption properties of various COF-based materials are assessed and compared with other widely used adsorbents. Several commonly used strategies to enhance COF-based materials’ adsorption performance and the relationship between structural property and sorption ability are also discussed. Finally, a summary and perspective on the opportunities and challenges of COFs and COF-based materials are proposed to provide some inspiring information on designing and fabricating COFs and COF-based materials for environmental pollution management.

“…Several synthetic routes were proposed for the preparation of Fe 3 O 4 @ZIF-8 composites. Most of them are based on a one-pot solvothermal synthesis of ZIF-8 in the presence of pre-prepared Fe 3 O 4 nanoparticles [ 17 , 18 , 19 , 20 , 21 ]. This simple strategy, however, results in a limited loading of the microporous component in Fe 3 O 4 @ZIF-8.…”

This work presents a novel approach to synthesizing magnetic core-shell nanocomposites, consisting of magnetic nanoparticles and a metal-organic framework, for environmental applications. The synthesis is based on the encapsulation of magnetic Fe3O4 nanoparticles with microporous zeolitic imidazolate framework-8 (ZIF-8) nanocrystals via ultrasonic activation under a continuous supply of precursor solutions. This sonochemical approach is proven to be a fast, cost-effective, and controllable route for the preparation of magnet-responsive Fe3O4@ZIF-8 nanoparticles with a core-shell structure. The functional nanomaterial possesses a high content of ZIF-8 and combined micro/mesoporosity, and thus can be used as adsorbents that can be easily separated using a magnet. In particular, the sonochemically prepared Fe3O4@ZIF-8 exhibits significant adsorption performance for the removal of copper ions from water: a short adsorption time (10 min), high maximum uptake capacity (345 mg g−1), and excellent removal efficiency (95.3%). These performances are interpreted and discussed based on the materials characteristics of Fe3O4@ZIF-8 established by microscopy, gas sorption, X-ray diffraction, and thermal analysis.

“…OM can also react with chlorine producing toxic by-products such as bromodichloromethane and dibromochloromethane (Ghernaout et al, 2009;Matilainen et al, 2010). There is a range of innovative methods used to remove organic and inorganic pollutants from water (Pang et al, 2019;Wu et al, 2019), such as the application of hybrid aerogels/perox-monosulfate to remove phenolic compounds, as much as 90 % of p-nitrophenol within 60 minutes (Ren et al, 2018). Metal-organic frameworks have also been used to develop hydrogels and other types of adsorbents (Wang et al, 2019;Wu et al, 2019).…”
