“…222 In contrast, with MIL-101−NH−SO 3 H, a band at 1207 cm −1 was proposed to be diagnostic for sulfur incorporation in the structure. 223 It was reported that the acidic carboxylic groups of MIL-101 functionalized by acrylic acid participate in adsorption of Sc 3+ ions. The conclusions were made on the basis of the strong decrease in the intensity of the CO band at 1712 cm −1 and the OH band at 3430 cm −1 (associated with the COOH moieties) after adsorption of Sc 3+ .…”

The variety of functionalities and porous structures inherent to metal-organic frameworks (MOFs) together with the facile tunability of their properties makes these materials suitable for a wide range of existing and emerging applications. Many of these applications are based on processes involving interaction of MOFs with guest molecules. To optimize a certain process or successfully design a new one, a thorough knowledge is required about the physicochemical characteristics of materials and the mechanisms of their interaction with guest molecules. To obtain such important information, various complementary analytical techniques are applied, among which vibrational spectroscopy (IR and Raman) plays an important role and is indispensable in many cases. In this review, we critically examine the reported applications of IR and Raman spectroscopies as powerful tools for initial characterization of MOF materials and for studying processes of their interaction with various gases. Both the advantages and the limitations of the technique are considered, and the cases where IR or Raman spectroscopy is preferable are highlighted. Peculiarities of MOFs interaction with specific gases and some inconsistent band assignments are also emphasized. Summarizing the broad analytical possibilities of the IR and Raman spectroscopies, we conclude that it can be applied in combinations with other techniques to explicitly establish the structure, properties, and reactivity of MOFs.

Poly(arylene ether)s (PAEs) engineering plastics are a type of high-performance material which are excellent in thermal resistance, mechanical properties, and have low dielectric constant and anti-corrosion. Over recent decades, PAEs further combined with the electrospinning technology to fabricate as large surface-to-volume ratio and porosity membrane materials for high-performance applications. In this review, progresses of PAEs-based electrospun nanofibers and fiber reinforced composites including proton/anion exchange membranes, oil-water separation membranes, bio-scaffolds and humidity sensors, etc. are presented together with their corresponding high-performance applications in the fields of fuel cell, wastewater treatment, bioengineering and flexible durable sensor. Finally, current challenges and future development directions of PAEs electrospun nanofibers are discussed.

Relative humidity (RH) is an important physical quantity in industry, agriculture, and medical treatment. However, it is still challenging to exploit high-performance humidity sensors that can meet the detection requirement for responding to both high humidity variation and low humidity variation. In this work, ternary graphitic carbon nitride (g-C 3 N 4 ) nanosheet/TiO 2 nanoparticle/Ti 3 C 2 T x nanosheet composites were synthesized by in situ oxidation and thermal polymerization. The response of the g-C 3 N 4 /TiO 2 /Ti 3 C 2 T x sensor reaches 531 from 11−95% RH, which enhances 4, 11, and 450 times compared with that of TiO 2 , g-C 3 N 4 , and TiO 2 /Ti 3 C 2 T x sensors. Moreover, the ternary g-C 3 N 4 /TiO 2 /Ti 3 C 2 T x sensor demonstrates excellent reproducibility, fast response speed, low hysteresis loop, and good anti-interference ability. The as-fabricated g-C 3 N 4 /TiO 2 /Ti 3 C 2 T x sensor is further utilized in practical applications for human respiration detection and evaluation of waxing of fruits. The test results show that our fabricated sensor is capable of precisely sensing breathing status and distinguishing the waxing of fruits. In addition, our sensor can be used in most application scenarios and accelerate the integration of the Internet of Things (IoT).
