“…90 In addition, a portable Eu-based MOFs fluorescent film was investigated and found suitable for the simultaneous fast detection of formaldehyde content in the liquid and gas phases. 91 In terms of gas adsorption, Rezaei et al investigated the coating of MOF-74(Ni) and UTSA-16(Co) onto the surface of commercial cordierite and optimized the properties such as the crystal growth and film thickness to produce a monolith wrapped with 55 wt % MOFs (Figure 4). 92 The CO 2 adsorption capacities of the coated MOF-74 and UTSA-16 were 1.7 and 1.1 mmol/g (1 bar), respectively, which were only 28% and 29% of the powder samples.…”

“…Jun et al reviewed the application of MOFs membranes in water purification and concluded that most of the modified films improved the selective permeability but only at the laboratory scale, and the water stability and recyclability of MOFs in practical applications must be considered . In addition, a portable Eu-based MOFs fluorescent film was investigated and found suitable for the simultaneous fast detection of formaldehyde content in the liquid and gas phases …”

Metal–organic frameworks (MOFs) have attracted a lot of attention in various applications such as molecular separation, catalysis, and gas delivery, due to their unique properties such as controllable structure, significantly specific surface area, and extensive porosity. However, conventional synthesis methods yield powdered MOFs, which cannot be directly used in the adsorption separation process due to such limitations as a high pressure drop, low mass transfer rate, and poor recyclability with scattering tendencies. Thus, it is crucial for practical applications to shape MOFs into various monoliths that allow an efficient processing, especially for industrial purposes. The existing forming methods are used to shape MOFs into films, pellets, tablets, gels, and honeycomb forms. At the same time, the shaping processes are generally accompanied by varying degrees of performance degradation of the original MOFs material, which is manifested in terms of loss of its adsorption capacity by a decrease in the specific surface area and porosity. Consequently, it is important to shape MOF monoliths into the appropriate shapes, mechanical strength, and stability, as well as to prevent the loss of the original properties in industrial applications. This paper reviews various strategies for shaping MOFs and discusses the impact of the shaping process on the properties of the MOFs as compared to their pristine powder form. It is believed this review will facilitate the industrial application of MOFs in gas processing applications.

“…23d). 159 The Eu-based MOF was prepared by reaction between Eu(NO 3 ) 3 6H 2 O and pyromellitic acid in the presence of anhydrous sodium acetate. Upon exposure to FA, the fluorescence of the ligand increased gradually with the concentration of FA, while the characteristic emission peak of Eu remained almost no change.…”

“…At present, there a variety of analytical techniques have been used to detect TDGA, such as gas chromatography [ 7 ], isokinetic electrophoresis [ 8 ], voltammetry [ 9 ] and liquid chromatography–mass spectrometry [ 10 ]. However, these methods are difficult to use for fast and real-time monitoring because of their complicated sample pretreatment, long processing time and inadequate detection limits [ 11 , 12 ]. Therefore, a simple and precise method for the rapid identification of TDGA levels is highly desirable.…”

Thiodiglycolic acid (TDGA) is a biomarker for monitoring vinyl chloride exposure. Exploring a facile, rapid and precise analysis technology to quantify TDGA is of great significance. In this research, we demonstrate a fluorescent sensor based on dual-emissive UiO-66 for TDGA detection. This ratiometric fluorescent material named C460@Tb-UiO-66-(COOH)2 was designed and synthesized by introducing organic dye 7-diethylamino-4-methylcoumarin (C460) and Tb3+ into UiO-66-(COOH)2. The as-obtained C460@Tb-UiO-66-(COOH)2 samples showed highly selective recognition, excellent anti-interference and rapid response characteristics for the recognition of TDGA. The detection limit is 0.518 mg·mL−1, which is much lower than the threshold of 20 mg·mL−1 for a healthy person. In addition, the mechanism of TDGA-induced fluorescence quenching is discussed in detail. This sensor is expected to detect TDGA content in human urine.
