In this study, we synthesized a water-stable Fe-based metal-organic framework, MIL-88B (Fe) by a solvothermal method, and for the first time, MIL-88B (Fe)/HRP composite was prepared for the degradation of bisphenol A (BPA) by immobilizing horseradish peroxidase on MIL-88B (Fe) using covalent fixation method. The material was characterized via XRD, FTIR, TG, and SEM methods. The results showed that the composite could remove bisphenol A quickly and efficiently by adding the hydrophilic agent polyethylene glycol, with the removal rate of BPA up to 99.2% within 1 hour. In addition, the initial concentration of bisphenol A, the dosage of the immobilized enzyme and the amount of H2O2 added had a great influence on the degradation efficiency. It was found that immobilized HRP could be reused, and its storage stability and thermal stability were better than free HRP. These show that immobilized enzymes have a broad application prospect in waste-water treatment.

“…In contrast, the Fe 2p high resolution spectrum of MCN-3 exhibits negatively shifted peaks, as compared to the pristine NH 2 -MIL-101(Fe), demonstrating more electrons acceptance by metal sites. 49 The result further indicates the formation of the heterojunction between NH 2 -MIL-101(Fe) and g-C 3 N 4 .…”

“…As compared with NH 2 -MIL-101(Fe), MCN-3 gives high intensity of N, which supports the presence of g-C 3 N 4 in the MCN-3. As shown in Figure b, the N 1s spectrum manifests four peaks at 397.8, 398.7, 399.7, and 400.8 eV corresponding to the N from Fe–N, C–NC, N–(C) 3 , and N–H X , respectively. − The C 1s spectrum of MCN-3 is shown in Figure c, which can be resolved to six peaks at 284.6, 284.7, 284.9, 286, 288.2, and 288.9 eV. Among these, the peaks at 284.6 and 284.7 eV can be assigned to the C–C and C–H, while the peaks at 286 and 288.2 eV can be attributed to the C–N–C and C–(N) 3 , respectively, in g-C 3 N 4 .…”

Visible light-driven photocatalytic reduction of CO 2 into value-added chemical fuel is considered as an up-and-coming pathway for CO 2 conversion utilizing green solar energy. Herein, we report heterostructures of NH 2 -MIL-101(Fe)/g-C 3 N 4 (g-C 3 N 4 = polymeric graphite-like carbon nitride) as prominent photocatalysts for the reduction of CO 2 via a solvent-free reaction. Among these heterogeneous photocatalysts, NH 2 -MIL-101(Fe)/g-C 3 N 4 -30 wt % referred to as MCN-3 shows superior catalytic activity for photocatalytic reduction of CO 2 to CO with a CO yield of 132.8 μmol g −1 , which is more than 3.6 times higher than that for pristine NH 2 -MIL-101(Fe) and 6.9 times higher than that for sole g-C 3 N 4 . In virtue of the elaborate designed photocatalysts and the gas−solid interfacial route, the heterostructure of NH 2 -MIL-101(Fe)/g-C 3 N 4 with efficient interfacial electron transfer between NH 2 -MIL-101(Fe) and g-C 3 N 4 results in the boosted photocatalytic reduction of CO 2 upon visible light irradiation.

“…MOF‐based materials, including pristine MOFs, MOF composites (e.g., C 3 N 4 /MOF composite, metal nanoparticles@MOF, and TiO 2 /MOF composite), and MOF‐derived materials are well studied for the catalysis purposes. For most MOFs are insulator, design MOF‐based materials as efficient catalysts for CO 2 reduction, their charge mobility, and electronic conductivity should be carefully considered.…”

www.advancedsciencenews.comreaction is more unfavorable. [22,23] Comparing to the researches on artificial H 2 production, the knowledge referring to efficient and selective reduction of CO 2 to energy-rich molecules is urgent to be updated. CO 2 conversion is often traced back to 1972 that reported by Honda and Fujishima with using inorganic photocatalysts TiO 2 . [24] As the capture of CO 2 has already been studied in metal-organic frameworks (MOFs), [25][26][27][28] it has recently been studied for their use as catalysts for the reduction of CO 2 into high-value chemicals. [14,29] MOFs hold great promise for applications in the field of CO 2 reduction, which can act directly as the catalysts or as components to promote CO 2 reduction in a hybrid catalytic system. The interior of MOFs can be designed to have open metal sites, specific heteroatoms, functionalized organic ligand, other building unit interactions, hydrophobicity, defects, porosity, and embedded nanoscale metal catalysts which is crucial for the development of better CO 2 reduction performance MOFs. [30][31][32] Due to the poor electron conductivity of MOFs, [33,34] and the inaccessibility of all the catalytic active sites to the reactants, the stability of MOFs in water and under UV light irradiation need to be further improved. We believe that a comprehensive and up-to-date review summarizing the recent applications of MOFs for CO 2 reduction will contribute to improve theoretical understanding of this field. In order to make a better achievement, it is necessary to use the MOF to build more complex materials to address CO 2 capacity and reduction ability together in one material. Future MOFs materials for CO 2 reduction should be economical and environmental friendly. The keys for promoting catalysis include structural defects in the MOFs, open metal sites from metal clusters, Lewis acid sites from the metal cluster and organometallic linker, and cocatalyst functionalized MOFs.Several reviews focusing on MOFs for CO 2 conversion have been recently reviewed and discussed. Dhakshinamoorthy et al. pointed out that photoexcitation of the light absorbing units in MOFs often generates a ligand-to-metal charge-separation state that can result in photocatalytic activity. Maina et al. discussed the corelationship between the properties of MOF materials including their CO 2 reduction catalytic performance under different reaction conditions. Li and co-workers have summarized the recent applications of MOFs for photocatalytic CO 2 reduction, in which MOFs can act as the photocatalysts for CO 2 reduction or as components in a hybrid photocatalytic system to promote CO 2 reduction. Yaghi and co-workers also pointed out that the challenge in developing catalysts for CO 2 photo-or electroreduction is rooted in the interplay between selectivity, activity, and efficiency. [35][36][37][38] Synthetic Approaches for MOFsMOFs, also called porous coordination polymers, are extended framework with open structures constructed from metal ions and organic ligands linked...
