“…The Fe 3 O 4 @PDA@BA-MOFs with ultrahigh surface area, uniform morphology, excellent hydrophilicity and strong magnetic responsiveness were demonstrated to have high selectivity, obvious binding kinetics, large adsorption capacity, and excellent reusability (above 91.23% at least six repeated adsorption-desorption cycles), which would be good candidates for the enrichment and purification of luteolin. Liu et al, prepared the magnetic composite of MOF-Fe 3 O 4 @HKUST-1/MIL-100(Fe) by LbL self-assembly method and applied it for the detection of methylene blue in foods [117]. Great recoveries in the range of 70-110% signified the application prospect of MMOFs as SPE adsorbent in the pretreatment of food matrices.…”

A variety of contaminants in food is an important aspect affecting food safety. Due to the presence of its trace amounts and the complexity of food matrix, it is very difficult to effectively separate and accurately detect them. The magnetic metal-organic framework (MMOF) composites with different structures and functions provide a new choice for the purification of food matrix and enrichment of trace targets, thus providing a new direction for the development of new technologies in food safety detection with high sensitivity and efficiency. The MOF materials composed of inorganic subunits and organic ligands have the advantages of regular pore structure, large specific surface area and good stability, which have been thoroughly studied in the pretreatment of complex food samples. MMOF materials combined different MOF materials with various magnetic nanoparticles, adding magnetic characteristics to the advantages of MOF materials, which are in terms of material selectivity, biocompatibility, easy operation and repeatability. Combined with solid phase extraction (SPE) technique, MMOF materials have been widely used in the food pretreatment. This article introduced the new preparation strategies of different MMOF materials, systematically summarizes their applications as SPE adsorbents in the pretreatment of food contaminants and analyzes and prospects their future application prospects and development directions.

“…demonstrated a facile layer‐by‐layer deposition together with an epitaxial growth route to produce Fe 3 O 4 @dual‐MOFs in Figure 9g. [ 146 ] They chose two models of MOFs with the same 1,3,5‐Benzenetricarboxylic acid (H 3 BTC) as the bridging organic linker, namely HKUST‐1 (Cubic, a = b = c = 26.52 Å) and MIL‐100 (Cubic, a = b = c = 73.34 Å), which are further used to synthesize the hierarchical structure. Meanwhile, the study on reaction kinetics around a series of substrates displays that the growth of HKUST‐1 extends along the [111] direction.…”

Multiporous metal‐organic frameworks (MOFs) have emerged as a subclass of highly crystalline inorganic‐organic materials, which are endowed with high surface areas, tunable pores, and fascinating nanostructures. Heterostructured MOF‐on‐MOF composites are recently becoming a research hotspot in the field of chemistry and materials science, which focus on the assembly of two or more different homogeneous or heterogeneous MOFs with various structures and morphologies. Compared with one single MOF, the dual MOF‐on‐MOF composites exhibit unprecedented tunability, hierarchical nanostructure, synergistic effect, and enhanced performance. Due to the difference of inorganic metals and organic ligands, the lattice parameters in a, b, and c directions in the single crystal cells could bring about subtle or large structural difference. It will result in the composite material with distinct growth methods to obtain secondary MOF grown from the initial MOF. In this review, the authors wish to mainly outline the latest synthetic strategies of heterostructured MOF‐on‐MOFs and their derivatives, including ordered epitaxial growth, random epitaxial growth, etc., which show the tutorial guidelines for the further development of various MOF‐on‐MOFs.
