“…Kuznicki et al [485] constructed two different Fe-MOF-based composites such as Fe-MIL-88 and Fe-MIL-101 for water adsorption, and the fabricated Fe-MIL-101 composite presented excellent water adsorption property than other MOF-based materials. Zu et al [486] fabricated the MIL-160(Al) composite for water harvesting, which demonstrated that such a MIL-160 (Al) composite is a promising material for highly efficient water adsorption. Tao et al [487] injected the metal foam into MOF structure for water capture, and the optimized metal foam/MOF composite presented improved water capture capacity.…”

Metal-organic framework-based compounds have recently gained great attention because of their unique porous structure, ordered porosity, and high specific surface area. Benefiting from these superior properties, metalorganic framework-based compounds have been proven to be one of the most potential candidates for environmental governance and remediation. In this review, the different types of metal-organic framework-based compounds are first summarized. Further, the various environmental applications of metal-organic framework-based compounds including organic pollutant removal, toxic and hazardous gas capture, heavy metal ion detection, gas separation, water harvesting, air purification, and carbon dioxide reduction reactions are discussed in detail. In the end, the opportunities and challenges for the future development of metal-organic framework-based compounds for environmental applications are highlighted.

“…For the harmonic-wave case, the RH changes between 33% and 75% within 24 hours based on the sine function (here, γ=0.5). The test material used in this paper is metal-organic frameworks (MIL-100) [16][17][18][19][20][21][22][23], which is a novel moisture adsorbent with large porosity and water uptake capacity. The weight of the samples was automatically measured and recorded to monitor the amount of moisture adsorbed or desorbed by the test samples.…”

Moisture transfer in buildings significantly affects indoor thermal comfort, energy consumption, and durability of construction materials. It is crucial to predict the moisture storage and transfer in building simulations accurately. However, moisture transfer was neglected in many simulation tools for building performance analysis. In those calculation tools, including a moisture model, moisture transfer has been either estimated by simple approximations or calculated by complex combined heat, air, and moisture transfer (HAMT) models that require orders of magnitude more computing time than simple calculations. In this study, a new moisture prediction model with fast solution time and reasonable accuracy was developed based on the moisture buffer value (MBV) theory. The moisture buffer value was initially designed to quantify the moisture buffering ability of porous building materials. Very little research has been conducted to use MBV for calculating building energy performance directly. This paper first studied the MBVs under different boundary conditions (i.e., square wave and harmonic wave variation of vapour content), and then a time-average MBV was proposed. Experiments were carried out to get the parameters for the new FMBM model. Finally, simulation tests were conducted to compare the FMBM model with other moisture prediction models (e.g. EC, EMPD and HAMT models). The results indicate that the FMBM can provide a fast and reasonably accurate solution for indoor moisture prediction.

“…Metal-Organic Framework (MOFs), a new class of porous sorbent material with tunable pore size and shape, chemical functionalization, and large porosity and surface area, has aroused excellent research interest recently [9]. Many MOFs have high adsorption capacity and very mild regeneration conditions, which makes MOF one of the best candidate materials for indoor environment control [10][11][12][13][14]. It has been proved that some MOFs can be used as excellent sorbent materials for VOC adsorption [15,16].…”

Volatile organic compounds (VOCs) are the major indoor air pollutants that affect human health, comfort, and working performance. Sorbent material and adsorption technology are considered to be one of the most effective and economical ways to remove VOCs from indoor air. Among many sorbent materials, metal-organic frameworks (MOFs) have received more and more attention because of their superior performance in capturing a variety of compounds. In this work, the adsorption characteristic of a newly synthesized pyrazole-based metal-organic framework (Al-pda) for different VOCs was investigated. First, the single-pass VOC adsorption rates of Al-pda and activated carbon were tested under different low-concentration VOCs mixture, which is in line with the practical application in the indoor environment. The results showed that Al-pda had an especially high adsorption ability for formaldehyde. The single-pass efficiency of formaldehyde adsorption was up to 89% at the beginning of the test and gradually stabilized at 66%. Compared with activated carbon, Al-pda had significantly higher selectivity and adsorption efficiency for the capture of formaldehyde. Then the effect of relative humidity on formaldehyde adsorption was investigated. After increasing the relative humidity from 15% to 65%, Al-pda’s formaldehyde single-pass adsorption rate almost remained at a similar level. Preliminary research showed that Al-pda is a promising material for the selective adsorption of indoor formaldehyde under humid conditions. More work is needed to probe this new MOF’s adsorption mechanism and application method.
