“…[17][18][19][20] For the goal of combining the advantages of both MOFs and IL S , IL-impregnated MOFs were synthesized for the adsorption of phenol derivatives. IL@MOF composites were previously studied for gas storage and separation, 21 dye removal, 22,23 or antibiotic adsorption. 24 In each of these situations, MOFs and ILs work in concert, producing a synergistic effect, to increase the adsorption performance of the obtained materials for the purpose of removing the target pollutants.…”

“…A number of methodologies for quantifying synthetic food colors have been developed, including solid-phase extraction (SPE) [ 15 ], high-performance liquid chromatography (HPLC) [ 16 ], thin-layer chromatography (TLC) [ 17 ], spectrophotometry [ 18 ], capillary electrophoresis [ 19 ], solid-phase spectrophotometry [ 20 ], and fluorescence emission spectroscopy [ 21 ]. However, these methods have several drawbacks, including the need for specialized equipment, a laborious preparation/measurement procedure, as well as requiring a skilled operator for exact analysis [ 22 , 23 ].…”

Food colorants are important in food selection because they improve the gastronomic appeal of foods by improving their aesthetic appeal. However, after prolonged use, many colorants turn toxic and cause medical problems. A synthetic azo-class dye called carmoisine gives meals a red color. Therefore, the carmoisine determination in food samples is of great importance from the human health control. The current work was developed to synthesis ZnO hollow quasi-spheres (ZnO HQSs) to prepare a new electrochemical carmoisine sensor that is sensitive. Field emission-scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) have been used to analyze the properties of prepared ZnO HQSs. A screen-printed graphite electrode (SPGE) surface was modified with ZnO HQSs to prepare the ZnO HQSs-SPGE sensor. For carmoisine detection, the ZnO HQSs-SPGE demonstrated an appropriate response and notable electrocatalytic activities. The carmoisine electro-oxidation signal was significantly stronger on the ZnO HQSs-SPGE surface compared to the bare SPGE. Cyclic voltammetry (CV), linear sweep voltammetry (LSV), chronoamperometry (CHA), and differential pulse voltammetry (DPV) have been utilized to investigate the suggested protocol. The DPV results revealed an extensive linear association between variable carmoisine concentrations and peak current that ranged from 0.08 to 190.0 µM, with a limit of detection (LOD) as narrow as 0.02 µM. The ZnO HQSs-SPGE’s ability to detect carmoisine in real samples proved the sensor’s practical application.

“…Zhu et al284 incorporated a pyridine IL into bimetallic MOF ([PrPy][Br]/MOF(Cu/Co)) for the separation of sunset yellow. The bimetallic [PrPy][Br]/MOF(Cu/Co) composite exhibited better recycling performance than the monometallic MOF, attributed to the synergistic effect between the bimetals in the bimetallic IL/MOF composite and the abundant tunable active sites.…”

Metal–organic frameworks (MOFs) and ionic liquids (ILs) represent promising materials for adsorption separation. ILs incorporated into MOF materials (denoted as IL/MOF composites) have been developed, and IL/MOF composites combine the advantages of MOFs and ILs to achieve enhanced performance in the adsorption-based separation of fluid mixtures. The designed different ILs are introduced into the various MOFs to tailor their functional properties, which affect the optimal adsorptive separation performance. In this Perspective, the rational fabrication of IL/MOF composites is presented, and their functional properties are demonstrated. This paper provides a critical overview of an emergent class of materials termed IL/MOF composites as well as the recent advances in the applications of IL/MOF composites as adsorbents or membranes in fluid separation. Furthermore, the applications of IL/MOF in adsorptive gas separations (CO2 capture from flue gas, natural gas purification, separation of acetylene and ethylene, indoor pollutants removal) and liquid separations (separation of bioactive components, organic-contaminant removal, adsorptive desulfurization, radionuclide removal) are discussed. Finally, the existing challenges of IL/MOF are highlighted, and an appropriate design strategy direction for the effective exploration of new IL/MOF adsorptive materials is proposed.
