“…The measured diffraction peaks of the MMOF composites were quite similar to those of bare Fe–Al MMH ( Figure 1 b–f). In addition, three characteristic peaks at 2θ values of 9.0, 18.0, and 33.0° were present in the XRD patterns of Fe–Al MMH@MOF(Fe–H 2 BDC) and Fe–Al MMH@MOF(Fe–H 2 BDC-NH 2 ) ( Figure 1 b,c), 23 , 24 while the XRD pattern of Fe–Al MMH@MOF(Fe–H 3 BTC) exhibited a peak at a 2θ value of 9.0° ( Figure 1 e). 25 There was no additional peak in the pattern of Fe–Al MMH@MOF(Fe–H 2 BDC-DH).…”

Magnetic sorbents based on iron–aluminum-mixed metal hydroxides composited with metal–organic frameworks (MOFs) were designed and synthesized using different benzoate ligands, including terephthalic acid, 2-aminoterephthalic acid, 2,5-dihydroxyterephthalic acid, 1,3,5-benzenetricarboxylic acid, and 1,2,4,5-benzenetetracarboxylic acid. The magnetic MOF derived from terephthalic acid ligand exhibited an excellent extraction efficiency, with adsorption capacities in the range of 2193–4196 mg kg –1 , and was applied for magnetic solid-phase extraction (MSPE) of carbamate pesticides, that is, bendiocarb, carbosulfan, carbofuran, carbaryl, propoxur, isoprocarb, and promecarb. Simple digital image colorimetry based on the diazotization reaction and high-performance liquid chromatography (HPLC) were utilized for fast screening and quantification purposes, respectively. A good analytical performance for a simple screening approach using portable equipment was obtained with detection limits in the range of 1.0–18.0 μg L –1 . Under the optimized MSPE-HPLC conditions, the entire developed procedure provided a wide linear range between 0.015 and 1000 μg L –1 , low limits of detection, and limits of quantitation ranging from 0.005 to 0.090 and 0.015–0.300 μg L –1 , respectively. Enrichment factors up to 184 were achieved. The intra- and interday relative standard deviations were below 6.7 and 9.4%, respectively. The proposed MSPE-digital image colorimetry and MSPE-HPLC methods were successfully applied for screening and determining carbamate pesticides in fruits and vegetables. The recoveries were obtained in a satisfactory range of 71.5–122.8%. This discovery has led to the development of integration methods using newly synthesized sorbent materials for the enrichment of carbamate pesticides prior to their analysis in complicated samples. The developed MSPE coupled with digital image colorimetry was efficient for fast carbamate contamination screening, while MSPE-HPLC offered a sensitive analytical methodology for quantifying contaminated samples.

“…The main disadvantages of g-C 3 N 4 are the limited electron migration rate caused by poor conductivity and the fewer active sites owing to the low specific surface area and poor hydrophilicity; these drawbacks make it necessary to explore other materials to obtain MOF-based type-II heterojunctions, such as metal oxides, chalcogenides, and perovskites (TiO 2 , 53,145 CdS, 146 WO 3 , 147,148 Bi 2 WO 6 ). 54,149,150 The photocatalytic activity of these heterojunctions is comparable to that of the MOF@g-C 3 N 4 composites.…”

Heterogeneous photocatalysis has been considered one of the most attractive alternative routes to transforming naturally abundant, clean, and sustainable solar energy into chemical energy. Nowadays, the most popular heterogeneous photocatalyst, titanium dioxide, has already found applications for water splitting to produce hydrogen and oxygen, for the degradation of organic pollutants, for air purification, and for the creation of self‐cleaning coatings. However, TiO2 has a significant limitation: a large band gap (3.0–3.4 eV) that makes it impossible to use anything other than ultraviolet illumination to initiate photocatalytic processes. With a focus on efficient solar‐energy utilization, the development of new photocatalysts that are sensitive to visible light is an important direction in the theory and practice of heterogeneous photocatalysis. In this regard, the use of metal–organic frameworks (MOFs) is an attractive route; they have emerged as an interesting class of materials for applications in photoreactions due to their flexible tunability in composition, structure, and functional properties, along with their facilitated adsorption towards chemicals and their efficient light absorption. Moreover, they can be composed with other semiconductors to produce heterojunctions (e.g., type‐II, Z‐scheme, and S‐scheme), whose effectiveness in photogenerated charge separation has already been proven by many examples. The present critical review reports progress over the last 5 years in the preparation and activity of metal–organic framework‐based heterojunction photocatalysts for the degradation of organic pollutants. © 2022 Society of Chemical Industry (SCI).

“…MIL101 (Fe), which is self-assembled by iron and bridging terephthalic acid molecules, exhibits great potential as a new photocatalyst and has attracted growing attention due to its visible-light response, hydrothermal stability, low cost, excellent hydrophilicity, and non-toxicity. 3,5,[32][33][34] Nevertheless, the photocatalytic activity of sole MIL101 (Fe) is unsatisfactory due to the easy recombination of photogenerated electron-hole pairs. 28,35 The construction of MIL101(Fe)-based heterostructures has been shown to be an efficient strategy to solve this problem.…”

BACKGROUND MIL101(Fe) has attracted growing attention as a potential new photocatalyst. However, the drawbacks of easy recombination of photogenerated electron–hole pairs result in unsatisfactory activity. RESULTS In this work, to enhance the photocatalytic activity of MIL101(Fe), CeO2 nanorods were attached on the surface of octahedral MIL101(Fe) to obtain a novel 1D/3D heterojunction CeO2/MIL101(Fe). The as‐synthesized samples were characterized by a series of methods. The photocatalytic activity of CeO2/MIL101(Fe) was investigated by photodegradation of tetracycline under visible‐light irradiation. Compared with pristine CeO2 and MIL101(Fe), the as‐prepared CeO2/MIL101(Fe) composite with CeO2 content of 10 wt% exhibited a superior photocatalytic activity, with a tetracycline (TC) degradation efficiency of 83.5% and a TOC removal rate of 55.7% within 120 min. CONCLUSION The enhanced photocatalytic performance is attributed to the efficient separation of photogenerated charge carriers resulting from the formation of type‐II heterojunction between CeO2 and MIL101(Fe). This work provides a new approach for the fabrication of MOF‐based photocatalysts with high activity. © 2022 Society of Chemical Industry (SCI).
