“…The formation process of the composites is similar to that of MOF‐5/GO . Interestingly, the addition of AC also improved the specific surface area of MOF‐199, as we reported previously . Nevertheless, the way that AC increases the specific surface area of MOF‐199 is different to that of GO.…”

Copper‐based metal–organic framework/graphene oxide (MOF‐199/GO) composites were prepared under hydrothermal conditions. The adsorption performances of the composites for CH3SCH3 and CH3CH2SH removal under ambient conditions were evaluated. The materials were characterized by XRD, FTIR spectroscopy, nitrogen adsorption/desorption, scanning electron microscopy (SEM), and X‐ray photoelectron spectroscopy (XPS). The composites exhibit a unique layered structure. MGO‐1 with 5 % GO shows a higher surface area than that of pristine MOF‐199 owing to the creation of new pores between the MOF‐199 and GO units. MGO‐1 has the best adsorption capacities for CH3SCH3 and CH3CH2SH, and the uptake reaches 6.12 and 4.31 %, respectively, because of the increased surface area and dispersive forces in the new pores. During the adsorption of CH3CH2SH, a chemical reaction results in the destruction of the MOF structure. However, reversible chemisorption was found for CH3SCH3 removal, as testified by fixed‐bed regeneration. Multiple adsorption/regeneration cycles show that the MGO composites are promising adsorbents for CH3SCH3 removal.

“…36 Additionally, the HG in the hybrid materials can protect the CUS from being occupied by excess unreacted organic ligands and solvent molecules, resulting in more exposure of the CUS in MOFs. 30,56 Additionally, most MOFs with metallic nodes are considered hydrophilic, and the adsorptive desulfurization capacity of Cu-BTC decreases rapidly in the presence of a small amount of water. 36,51 HG can be considered hydrophobic due to the limited number of polar functional groups on its surface, which means it can retain a high level of aromaticity to repel water molecules.…”

“…The use of MOFs to filter H 2 S has been reviewed previously, most recently by Bobbitt et al Typically, H 2 S will bind to open metal sites, such as those in the extensively reported HKUST‐1, resulting (in that case) in breakdown of the MOF structure and the formation of copper sulfide. Interestingly, several composites of this MOF have shown apparently synergistic effects, including the graphite oxide/MOF composites reported by Bandosz and co‐workers and also the MOF/activated carbon composites reported by Shi et al In the latter study (reported in 2017 and hence not described in the aforementioned reviews), incorporation of less than 2% of activated carbon into the composites resulted in a 51% increase in H 2 S uptake; this was attributed to increased microporosity and availability of copper sites for reaction.…”

The quest for advanced designer adsorbents for air filtration and monitoring hazardous trace gases has recently been more and more driven by the need to ensure clean air in indoor, outdoor, and industrial environments. How to increase safety with regard to personal protection in the event of hazardous gas exposure is a critical question for an ever-growing population spending most of their lifetime indoors, but is also crucial for the chemical industry in order to protect future generations of employees from potential hazards. Metal-organic frameworks (MOFs) are already quite advanced and promising in terms of capacity and specific affinity to overcome limitations of current adsorbent materials for trace and toxic gas adsorption. Due to their advantageous features (e.g., high specific surface area, catalytic activity, tailorable pore sizes, structural diversity, and range of chemical and physical properties), MOFs offer a high potential as adsorbents for air filtration and monitoring of hazardous trace gases. Three advanced topics are considered here, in applying MOFs for selective adsorption: (i) toxic gas adsorption toward filtration for respiratory protection as well as indoor and cabin air, (ii) enrichment of hazardous gases using MOFs, and (iii) MOFs as sensors for toxic trace gases and explosives.
