“…Neat ZiF-8 showed lower performance than functionalized ZIF-8 for H 2 S and CO 2 removal. [80] Daraee et al produced TOUO-x nanocomposites by hydrothermal method and evaluated their performances in H 2 S, capturing at 30 to 50 °C the 4000 ppm H 2 S concentrations in feed under dynamic condition. TOUO-1 % exhibited a better adsorption capacity than other nanocomposites at 30 °C (Fig- ure ).…”

Removal of sulfur-containing compounds from liquid and gas steams originated from various processes of chemical industries would be essential, since these compounds can be the principal sources of deterioration and environmental degradation, and pollution even at low threshold concentration levels. The metal-organic frameworks (MOFs) compromise a wideranging of chemical structure designs with adjustable pore size and high promising surface area for the desulfurization process.In this review study, the current published studies and researches about sulfur removal in liquid and gas purification processes using MOFs as highly effective adsorbents and catalysts are systematically gathered and compared. According to the broad contextual information for sulfur removal using different MOFs in this study, it is called for new insight windows opened for the advance progresses in this area and the project of new and more effective MOF-based sorbents.

“…In the case the ZIF-8 NPs are functionalized, it is estimated that the Pb(Ac) 2 dyes are recrystallized on the ZIF-8 NPs during the dye-size reduction, that is, the melting and subsequent quenching process. In this sense, gas capturing properties of ZIF-8 can accelerate the chemical reactions between the adsorbed target analytes and the dyes coated on, leading to a higher-contrast change in the color. , The color change sensing tests were conducted by exposing the yarn@Pb(Ac) 2 _ILs, yarn@Pb(Ac) 2 _ILs_Al 2 O 3 , and yarn@Pb(Ac) 2 _ILs_ZIF-8 sensors, to 1 ppm of H 2 S for 10–60 s and 3 ppm of H 2 S for 60 s, in which the corresponding ΔRGB values demonstrate the enhancement in sensitivity (Figure S12). Based on these observations, we concluded that the sensing performance can potentially be further optimized by introducing specific additives.…”

Colorimetric Dye-Loaded Nanofiber Yarn: Eye-Readable and Weavable Gas Sensing Platform

et al. 2020

The colorimetric gas sensor offers an opportunity for the simple and rapid detection of toxic gaseous substances based on visually discernible changes in the color of the sensing material. In particular, the accurate detection of trace amounts of certain biomarkers in a patient's breath provides substantial clues regarding specific diseases, for example, hydrogen sulfide (H 2 S) for halitosis and ammonia (NH 3 ) for kidney disorder. However, conventional colorimetric sensors often lack the sensitivity, selectivity, detection limit, and mass-productivity, impeding their commercialization. Herein, we report an inexpensive route for the meter-scale synthesis of a colorimetric sensor based on a composite nanofiber yarn that is chemically functionalized with an ionic liquid as an effective H 2 S adsorbent and lead acetate as a colorimetric dye. As an eyereadable and weavable sensing platform, the single-strand yarn exhibits enhanced sensitivity supported by its high surface area and well-developed porosity to detect the breath biomarker (1 ppm of H 2 S). Alternatively, the yarn loaded with lead iodide dyes could reversibly detect NH 3 gas molecules in the ppm-level, demonstrating the facile extensibility. Finally, we demonstrated that the freestanding yarns could be sewn into patterned textiles for the fabrication of a wearable toxic gas alarm system with a visual output.

“…Ethylenediamine (ED) treated ZIF-8 nanoparticles enhanced the selectivity of CO2/CH4 by 37% compared to untreated ZIF-8 [203] . It can remove H2S and CO2 from natural gas [204] . The use of nanoparticles such as carboxylated carbon nanotubes (CNTs) composite prevented the aggregation of ZIF-8 in the membrane, increased the free volume of the MMM, and enhanced the CO2 adsorption performance and CO2/N2 separation performance [160] .…”

Carbon dioxide (CO2) is one of the culprit causes of global climatic changes. Furthermore, the efficient separation of CO2 from other gaseous mixtures using ZIFs-based materials is vital for several processes such as flue gas separation, gas sweetening, and natural gas processing. Zeolitic imidazolate frameworks (ZIFs)-based materials are emerging adsorbents and catalysts for CO2 gas removal via adsorption and conversion into valuable chemicals. ZIFs-based adsorbents with high adsorption/conversion efficiencies and tunable properties can be achieved by judicious synthesis and fabrication methods. We reviewed ZIF-based materials for CO2 removal via adsorption and catalysis (e.g., cycloaddition, carboxylation, hydrogenation, N-formylation, electrocatalysis, and photocatalysis). In addition, recent development methods such as membrane synthesis and ways to improve the gas separation performance of ZIF membranes were highlighted. The prospective point of view to promote industrial applications and commercialization of ZIF-based materials was briefly discussed. Once challenges such as low performance and reproducibility for ZIFs-based materials are solved, scalability and cost-effectiveness should not become issues.
