“…To date, some nanostructured materials receive increasing interests for determination or adsorption of Hg 2+ in the application of environmental governance, such as aptamer‐functionalized fluorescence probes, [ 12 ] gold‐bearing nanorod, [ 11b ] color‐changeable photonic crystals (PCs), [ 13 ] thiol‐modified graphene, [ 14 ] silica‐gelatin aerogel, [ 15 ] and metal–organic framework. [ 16 ] Among them, in view of better sensitivity of human vision to color perception, colored PCs with periodic alternation of refractive index, integrating stimuli responsive mechanism, and inherent optical or visual signal conversion capacity, offer an amenable design strategy for preparing smart sensing materials.…”

Mercury ion (Hg2+) contamination is a worldwide serious environment problem; exploring smart sensing and adsorption materials are urgently demanded for Hg2+ monitoring and removal. Herein, a simple 1D photonic crystal to first ever feature capabilities of visually quantitative determination and effective adsorption toward Hg2+ is facilely constructed by integrating a specifically designed thiourea‐functionalized nanocopolymer layer with a mesoporous TiO2 layer. Based on strong chelation and porous structure, Hg2+ is easily adsorbed on the copolymer and triggers vertically volumetric shrinkage, resulting in highlighted wavelength blue‐shifts and color changes in a broad Hg2+ level scope. Utilizing the adsorption characteristic, Hg2+ existing in aqueous media can be effectively removed by the photonic film with a remarkable uptake capacity of 739.6 mg g−1. This portable nanolayered film exhibits full regeneration, facile recovery, desirable selectivity toward Hg2+, and shields interference from other metal ions, which enables future application for environmental determination and remediation. Furthermore, a novel nanopolymer‐based two‐regime Hg2+‐capturing mechanism is first revealed by quartz crystal microbalance with dissipation monitoring, providing valuable references for future relevant adsorption researches.

“…Recently, Mon et al with a BET specific surface area of 659 m 2 /g. [205] This synthesized MTV-MOF, at a dose of only 50 mg, suggested a remarkable heavy metal ion capture capacity via sulfur-heavy metal ions affinity, such as forming sulfur-Hg 2+ bond, with complete removal of Hg 2+ , Pb 2+ , and Tl + within 210 min from 20 mL aqueous solution at initial metal ion concentration of 1 ppm at pH 7.0. These efficient sorbents employing functionalized MOFs provided feasible strategies for heavy metal ion removal to improve food safety especially the water quality.…”

“…[203] Therefore, removal of heavy metal ions is significant in food safety. In the last decade, a dramatic increase of developing MOFs to remove heavy metal ions for the improvement of food safety was reported because of a great number of advantages of MOFs as porous heavy ion sorbents, [204][205][206] which were reported in an overview by Feng and co-workers. [188] Lv et al employed MIL-101-NH2 as a sorbent to study the dynamic absorption of Fe 3+ , Cu 2+ , and Pb 2+ based on the fluorescence quenching determination of NH2-BDC ligand.…”

Investigation on food safety and preservation is essential to provide high quality and safe food for human beings, including accurate determination and efficient removal of inorganic heavy metal ions and organic contaminants, as well as regulation of food postharvest ripening and intelligent sterilization. In the last two decades, metal-organic frameworks (MOFs), as functionalized porous materials, have aroused interests of researchers because of their advantages of high porosity, large specific surface area, flexible structure properties, and abundant binding sites for guest molecules. MOFs have shown great potentials in practical applications in food and related fields. In this overview, we summarized the MOF crystallization mechanisms, synthesis routes and methods, stability, as well as the applications in food contamination including removal of heavy metal ions, dyes, and antibiotics, and food preservation including regulation of fruit and vegetable ripening, removal of moisture and oxygen, and high-efficiency sterilization. Finally, two perspectives focusing on the development of MOFs for innovative food research, i.e., food-grade MOFs and MOF composites are suggested based on our understanding.

A series of coordination polymers (CPs) based on phosphonates, M‐VP, and M‐Phen‐VP (M = Ce, La, Phen = 1,10‐phenanthroline, Im‐imidazole, VP = vinylphosphonate) were obtained by hydrothermal reactions in different conditions: room temperature, 75°C, 180°C, at pH 1.5–7 aqueous solutions. The materials were characterized by Fourier‐transform infrared (FTIR), X‐ray powder diffraction, and thermogravimetric analysis. The samples are characterized by a high degree of crystallinity, judging from the intensity of the peak in the 2θ region 8–9°. Thermogravimetric analysis performed on cerium and lanthanum CPs crystals indicate that the compounds are stable up to 360°C, after which it undergoes degradation corresponding to loss of the organic unit. The obtained materials were further used as adsorbent in the removal process of cesium (Cs(I)) and thalium ions (Tl(I)) from aqueous solutions. In order to establish the maximum adsorption capacity of the studied CPs and for the interpretation of the results obtained in the equilibrium study, several empirical isotherms were used: Freundlich, Temkin, Langmuir, and Dubinin–Radushkevich. The particular parameters for each isotherm and correlation coefficient (R2) have been determined.
