“…Compared with other fillers, the organic ligands provide more desired interactions with the surrounding polymer [252]. Moreover, the shape and size of the pores, as well as the chemical functionality, can be highly modulated by proper alteration of the metal node-organic ligand pairs [253]. Furthermore, due to their selectivity with enhanced gas permeability the problems of polymeric membranes can be overcome [254].…”

Gas sensing materials, such as semiconducting metal oxides (SMOx), carbon-based materials, and polymers have been studied in recent years. Among of them, SMOx-based gas sensors have higher operating temperatures; sensors crafted from carbon-based materials have poor selectivity for gases and longer response times; and polymer gas sensors have poor stability and selectivity, so it is necessary to develop high-performance gas sensors. As a porous material constructed from inorganic nodes and multidentate organic bridging linkers, the metal-organic framework (MOF) shows viable applications in gas sensors due to its inherent large specific surface area and high porosity. Thus, compounding sensor materials with MOFs can create a synergistic effect. Many studies have been conducted on composite MOFs with three materials to control the synergistic effects to improve gas sensing performance. Therefore, this review summarizes the application of MOFs in sensor materials and emphasizes the synthesis progress of MOF composites. The challenges and development prospects of MOF-based composites are also discussed.

Membrane separation processes are prevalent in industrial wastewater treatment because they are more effective than conventional methods at addressing global water issues. Consequently, the ideal membranes with high mechanical strength, thermal characteristics, flux, permeability, porosity, and solute removal capacity must be prepared to aid in the separation process for wastewater treatment. Rubber-based membranes have shown the potential for high mechanical properties in water separation processes to date. In addition, the excellent sustainable practice of natural fibers has attracted great attention from industrial players and researchers for the exploitation of polymer composite membranes to improve the balance between the environment and social and economic concerns. The incorporation of natural fiber in thermoplastic elastomer (TPE) as filler and pore former agent enhances the mechanical properties, and high separation efficiency characteristics of membrane composites are discussed. Furthermore, recent advancements in the fabrication technique of porous membranes affected the membrane’s structure, and the performance of wastewater treatment applications is reviewed.

“…Wrapped MoS 2 is a polar substance and a catalyst, providing more active sites for nanocomposites. , Additionally, some electroactive MOFs such as Cu-based MOFs (tricopper benzene-1,3,5-tricarboxylate, CuBTC), possessing a three-dimensional (3D) porous honeycomb-like network, consist of blank metal sites to receive adsorbate molecules, which exhibit excellent catalytic performance and superior electric conductivity . CuBTC is also thermostable and could be easily synthesized with relatively cheaper precursors compared to most of the MOFs …”

Metal−organic frameworks (MOFs) are composed of metal ions/clusters and organic ligands, showing accessible functional sites, ultra-high porosity, and large specific surface area. Tricopper benzene-1,3,5-tricarboxylate (CuBTC), as a three-dimensional MOF architecture with an open and robust micro-/nanoconfiguration, possesses excellent catalytic performance and superior electric conductivity as compared to bulk MOF. In this study, CuBTC was used as a substrate on which molybdenum disulfide (MoS 2 ) was in situ constructed by a hydrothermal reaction to enhance the electronand ion-transfer capability. Then, gold nanoparticles (AuNPs) were electroreduced on a CuBTC@MoS 2 -modified electrode by linear sweep voltammetry for strengthening the connection between CA125 antibodies (CA125 Ab) and the substrate material. Due to the synergistic effect of CuBTC@MoS 2 and AuNPs, our biosensor showed excellent electrochemical performance. Subsequently, CuBTC@MoS 2 -AuNPs/CA125 Ab-functionalized electrodes were used for the detection of the ovarian cancer biomarker CA125 from 0.5 mU/mL to 500 U/mL by differential pulse voltammetry. The results showed that the peak current decreased with the increase of concentration, and there was a logistic regression relationship between peak current variation and concentration. As interfering substances, carcinoembryonic antigen, human epididymis protein 4, and bovine serum albumin were applied for specific analysis. Our biosensor showed an obviously large response signal for CA125 detection than those observed for other interfering substances. Finally, serum samples collected from five patients were tested on our sensors with good consistency toward clinical standards, showing high practicability. This work demonstrated a tactic for simultaneously integrating the nanostructure, electroconductivity, and biocompatibility to construct advanced biosensors for cancer biomarkers.
