Metal–organic frameworks (MOFs) have attracted recently considerable attention in analytical sample preparation, particularly when used as novel sorbent materials in solid-phase microextraction (SPME). MOFs are highly ordered porous crystalline structures, full of cavities. They are formed by inorganic centers (metal ion atoms or metal clusters) and organic linkers connected by covalent coordination bonds. Depending on the ratio of such precursors and the synthetic conditions, the characteristics of the resulting MOF vary significantly, thus drifting into a countless number of interesting materials with unique properties. Among astonishing features of MOFs, their high chemical and thermal stability, easy tuneability, simple synthesis, and impressive surface area (which is the highest known), are the most attractive characteristics that makes them outstanding materials in SPME. This review offers an overview on the current state of the use of MOFs in different SPME configurations, in all cases covering extraction devices coated with (or incorporating) MOFs, with particular emphases in their preparation.

A facile strategy of uniform flower-shaped binary-metal-based metal-organic frameworks (MOFs) has been successfully synthesized via a simple hydrothermal method as the precursor of porous Mn2NiO4 nanostructures. After heat treatment at different temperatures, the as-prepared Mn2NiO4 inherits the morphologies of MOFs and can hold until 450°C. This porous Mn2NiO4, used as supercapacitor electrodes, exhibits a high specific capacitance (531.5 F g-1 at a current density of 1.0 A g-1), with a relatively high specific surface area (114.2 m2 g-1). The high capacitance is mainly attributed to the porous and hierarchical structure, which facilitates fast diffusion of active ions, improves structural stability and large contact area between Mn2NiO4 and the electrolyte. The developed synthetic strategy may provide design guidelines for constructing advanced ternary nanostructured supercapacitors electrode.

Metal Complex Catalysts

Metal–organic frameworks (MOFs) have emerged as novel photocatalysts owing to their inherent structural characteristics of a large surface area and a well-ordered porous structure. In this article, we summarize various strategies carried out over MOFs via either modification of the organic linker/metal clusters or incorporation with metal/complex catalysts to enhance the light absorption, charge separation, reactant adsorption/activation of MOF-based photocatalysis towards the superior photocatalytic performance.

We investigated the removal of a harmful anionic dye, acid orange 7 (AO7), from aqueous solution using metal-organic frameworks (MOFs). We prepared four different MOFs (ZIF-8, ZIF-67, UiO-66, UiO-66-NH2) by solvothermal reactions and then tested their adsorption of AO7. Infrared spectra and adsorption capacity data confirmed the removal of AO7 from aqueous solution. The factors we investigated affecting adsorption capacity include variation of the organic linkers and metal clusters of the MOFs. Our results suggest that the hydrogen bonding, π–π interactions, and zeta potentials facilitate the removal of AO7 from water. Of the four MOFs examined, ZIF-67 exhibited the highest adsorption capacity of AO7 and can be regenerated easily.
