“…Besides these, carbon nanomaterials, nano-biochar, silica nanomaterials, etc. are also commonly used for the removal of VOCs [ 70 , 71 , 72 , 73 ]. Some of the commonly used nanomaterials for the removal of VOCs include graphene-based nanomaterials, mesoporous organosilica nanomaterials, carbon nanomaterials, etc.…”

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.

“…Our laboratory has had a long-standing interest in exploring functional nano- and micro-scale materials for environmental remediation [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Recently, we developed a route to access poly(ethylenimine)-modified cellulose nanocrystals (PEI- f -CNC) that are capable of capturing volatile organic compounds associated with odors [ 22 ] and degrading common pesticides from water [ 27 ].…”

We have previously demonstrated that cellulose nanocrystals modified with poly(ethylenimine) (PEI-f-CNC) are capable of capturing volatile organic compounds (VOCs) associated with malodors. In this manuscript, we describe our efforts to develop a scalable synthesis of these materials from bulk cotton. This work culminated in a reliable protocol for the synthesis of unmodified cellulose nanocrystals (CNCs) from bulk cotton on a 0.5 kg scale. Additionally, we developed a protocol for the modification of the CNCs by means of sequential 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) oxidation and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) coupling to modify their surface with poly(ethylenimine) on a 100 g scale. Subsequently, we evaluated the performance of the PEI-f-CNC materials that were prepared in a series of VOC capture experiments. First, we demonstrated their efficacy in capturing volatile fatty acids emitted at a rendering plant when formulated as packed-bed filter cartridges. Secondly, we evaluated the potential to use aqueous PEI-f-CNC suspensions as a spray-based delivery method for VOC remediation. In both cases, the PEI-f-CNC formulations reduced detectable malodor VOCs by greater than 90%. The facile scaled synthesis of these materials and their excellent performance at VOC remediation suggest that they may emerge as a useful strategy for the remediation of VOCs associated with odor.

“…This e ciency in molecules transfer improves the lifetime of the MO and catalytic activity by minimizing the pore-blocking possibility by guest molecules [25][26][27] . This is because the organosilica motif of conventional mesoporous silicas stay on the external surface of pore channels while in MOs, it can be embedded in the pore wall 28,29 .…”

Hybridization of mesoporous organosilica (MO) to reinforce the surface capability in adsorption and stabilization of noble metal nanoparticles are of great attention in generating noble metal-based catalysts. Here, we used a unique hybrid of organic-inorganic mesoporous silica which in pore profile pattern was similar to the well-known mesoporous silica, SBA-15. This hybrid mesoporous silica was further incorporated in the synthesis and stabilization of Pd nanoparticles on its surface and then, the obtained Pd supported MO, was employed as a heterogeneous green catalyst in the conversion of p-nitrophenol (PNP) to p-aminophenol (PAP) at room temperature with efficient recyclability.
