“…Following the logic of the invention of adsorbents, Szczesniak et al fabricated the graphene/aluminum‐based MOFs composite which exhibited an ultrahigh benzene adsorption capacity of 33.6 mmol/g 8 . Additionally, MOFs‐based composites also can be utilized to detect VOCs because of their sensitive and selective adsorption ability 9–11 . It has been demonstrated that the ZnO@ZIF‐8 core‐shell materials were efficient in sensing ethanol than the pristine ZnO microsphere and ZIF‐8 12 .…”

Coupling with electrospinning technique, metal–organic‐frameworks (MOFs)‐derived porous carbon fibers exhibit a great potential application in the adsorption of volatile organic compounds (VOCs) because of their huge surface area, high porosity, as well as sufficient heteroatom‐doped active sites. In this work, the hierarchically porous N‐doped carbon nanofibers are obtained after the pyrolysis of zeolite imidazole framework‐8 and polyacrylonitrile (ZIF‐8/PAN) composite fibers synthesized by electrospinning method. The N‐doped carbon nanofibers fabricated in N2 atmosphere (N‐CF‐N2) present an enhanced adsorption capacity of 694 mg/g for benzene because of the synergistic effect of the hierarchically porous structure and the abundant N‐species‐containing active sites. It is also interesting that the N‐doped hierarchical carbon nanofibers fabricated in Ar atmosphere (N‐CF‐Ar) exhibit a low benzene adsorption as compared with the N‐CF‐N2, which can be attributed to the porous structure damage caused by the bombardment of heavy Ar atoms on the pore shells during the pyrolysis. These results not only show a promising application of the as‐fabricated N‐CF‐N2 in adsorption of VOCs for air purification due to its merit of cost‐efficient, large‐scale production, and excellent adsorption capacity, but also expand the potential of electrospinning technology and composite fibers in volatile organic gas adsorption.

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.

“…Similarly altering the surface hydrophobicity can bring about a difference in adsorption. Thus by changing one or more of the surface properties of the interacting surfaces, adsorption can be made more selective (Jiang et al, 2016;Attwood et al, 2019;Boudjema et al, 2020;Yu et al, 2020).…”

Bacillus cereus bacteria and their by-products were used as surface-active agents for surface hydrophobicity of the apatite in the flotation process leading to phosphate ores' enrichment. Recently, proteomics is used to investigate the biochemical processes through discovering new proteins or investigating protein-protein interactions. In this work, we investigated the physicochemical behavior of pure apatite and quartz minerals in the presence of Bacillus cereus using zeta-potential, FTIR, and hydrophobicity measurements. Our results indicated that isoelectric point (IEP) occurred at pH 4.7 for apatite and 2.1 for quartz mineral. Bacillus cereus treatment decreased IEP of apatite to 1.8; while there was no significant change in IEP value of quartz. We used comprehensive proteomic profile analysis of Bacillus cereus in the presence of apatite mineral to identify the biological mechanism and molecules involved in such enrichment capacity. Our data identified the up-regulated Surface Layer (S-Layer) protein in this bacterial strain to be associated with the best mineral yield.
