“…Nucleophilic aromatic substitution can also be used for longitudinal polymerization of PAs, as shown by He et al, who used a cotton fiber pre-grafted with TFP as solid support. 51 Pillar [5]arene-based COP was formed on the surface of the fibers by nucleophilic aromatic substitution of -OH groups of pillar [5]arene by TFP (Scheme 5C). Both reactions were carried out in a 9:1 mixture of THF:H 2 O in the presence of K 2 CO 3 at 80 C for 48 h. Functionalization of the cotton fiber resulted in a change of smooth surface to a rougher one with a coarse grafting layer and improved uptake of various pollutants in water and VOCs relative to free cotton.…”

“…In this context, the effective and efficient removal of volatile organic compounds from the environment is inevitable and has attracted a great deal of attention from researchers. Commonly used techniques for the removal of VOCs include thermal and catalytic oxidation, adsorption, condensation, bio-filtration, membrane separation, UV-oxidation, catalytic oxidation, and surface modification [ 44 , 45 , 46 ]. Some of the common methods for the removal of VOCs are given in Table 1 .…”

Air is the most crucial and life-supporting input from nature to the living beings of the planet. The composition and quality of air significantly affects human health, either directly or indirectly. The presence of some industrially released gases, small particles of anthropogenic origin, and the deviation from the normal composition of air from the natural condition causes air pollution. Volatile organic compounds (VOCs) are common contaminants found as indoor as well as outdoor pollutants. Such pollutants represent acute or chronic health hazards to the human physiological system. In the environment, such polluted gases may cause chemical or photochemical smog, leading to detrimental effects such as acid rain, global warming, and environmental pollution through different routes. Ultimately, this will propagate into the food web and affect the ecosystem. In this context, the efficient removal of volatile organic compounds (VOCs) from the environment remains a major threat globally, yet satisfactory strategies and auxiliary materials are far from being in place. Metal–organic frameworks (MOFs) are known as an advanced class of porous coordination polymers, a smart material constructed from the covalently bonded and highly ordered arrangements of metal nodes and polyfunctional organic linkers with an organic–inorganic hybrid nature, high porosities and surface areas, abundant metal/organic species, large pore volumes, and elegant tunability of structures and compositions, making them ideal candidates for the removal of unwanted VOCs from air. This review summarizes the fundamentals of MOFs and VOCs with recent research progress on MOF-derived nanostructures/porous materials and their composites for the efficient removal of VOCs in the air, the remaining challenges, and some prospective for future efforts.

“…The cupric oxide nanoparticles (CuONPs) have been used for adsorptive removal of benzene and toluene from aqueous environments [17]. Due to previous studies, the different methods such as, adsorption [18,19], the photo-catalytic oxidation and thermal oxidation [20] were used for removal of VOC's or BTEX in environment matrixes. Teimoori et al (2020) showed that the benzene can be extracted and determined in waters and wastewater samples based on functionalized carbon nanotubes (R-CNTs) using GC-FID.…”

In this study, the mixture of nano activated carbon (NAC) and ionic liquid (3-triphenylphosphonio-propane-1-sulfonate; C21H21O3PS) was coated on fused silica fiber of SPME holder (NAC-IL-FSF/SPME). Then NAC/IL was used for determining of benzene in soil and vegetables samples (1.0 g, n=50) surrounding a chemical industry zone. After benzene adsorption on NAC-IL based on head space solid phase micoextraction (HS-SPME), the concentration of benzene was simply determined by introducing probe to injector of gas chromatography with flame-ionization detection (GC-FID). All effected parameters such as the sorbent mass, the amount of sample, the temperature, and the interaction time were optimized in glass chromatography vials by static procedures. The benzene vapor was absorbed from soil and vegetables samples with NAC-IL-FSF/SPME holder for 10 min at 80oC (10 mg of NAC and 0.1 g of ionic liquid in 0.5 mL of acetone coated on FSF). Then the benzene was desorbed and determined by GC-FID spectrometry. The extraction efficiency and absorption capacity of adsorbent were obtained 98.5% and 127.2 mg g-1, respectively. The high surface area of NAC and favorite interaction of aromatic chain in IL (π-π), caused to efficiently remove of benzene vapor by HS-SPME procedure as compared to other nanostructures.
