“…Metal-organic frameworks (MOFs), as a new generation of porous functional materials, have been arousing extensive interest for their tunable attributes and expansive applications, spanning gas storage and separation, sensing, environmental decontamination, energy storage and conversion, and heterogenous catalysis. [1][2][3][4][5][6][7][8][9][10] In virtue of many well-developed construction strategies, hundreds of thousands of MOFs are obtained through direct or post-synthetic approaches, contributing enormous structural and functional diversity. [11][12][13][14] Despite a few robust MOFs, such as the famous UiO, [15,16] ZIF, [17,18] MOF, [19][20][21][22] MIL, [23,24] PCN, [25][26][27] and NU series, [28,29] most of existing MOFs are far away from practical use due to their relatively weak stability.…”

Despite numerous inherent merits of metal-organic frameworks (MOFs), structural fragility has imposed great restrictions on their wider involvement in many applications, such as in catalysis. Herein, a strategy for enhancing stability and enabling functionality in a labile Zr(IV)-MOF has been proposed by in situ porphyrin substitution. A size-and geometry-matched robust linear porphyrin ligand 4,4′-(porphyrin-5,15-diyl)dibenzolate (DCPP 2− ) is selected to replace the 4,4′-(1,3,6,8-tetraoxobenzo[lmn][3,8]phenanthroline-2,7(1H,3H,6H,8H)-diyl)dibenzoate (NDIDB 2− ) ligand in the synthesis of BUT-109(Zr), affording BUT-110 with varied porphyrin contents. Compared to BUT-109(Zr), the chemical stability of BUT-110 series is greatly improved. Metalloporphyrin incorporation endows BUT-110 MOFs with high catalytic activity in the photoreduction of CO 2 , in the absence of photosensitizers. By tuning the metal species and porphyrin contents in BUT-110, the resulting BUT-110-50%-Co is demonstrated to be a good photocatalyst for selective CO 2 -to-CO reduction, via balancing the chemical stability, photocatalytic efficiency, and synthetic cost. This work highlights the advantages of in situ ligand substitution for MOF modification, by which uniform distribution and high content of the incoming ligand are accessible in the resulting MOFs.More importantly, it provides a promising approach to convert unstable MOFs, which mainly constitute the vast MOF database but have always been neglected, into robust functional materials.

The severe acute respiratory syndrome coronavirus (SARS-CoV-2) pandemic of 2019 forced widespread use of face coverings as a mandatory step towards reducing infection by the virus. The face mask acts as a barrier for transmission of infected aerosols among its user and surrounding people. This has propelled pace of research and development of face masks around the world. This short review is an effort to present advances in materials and designs used for face masks. Details available in scientific literature and company brochures have been accessed and the use of nanomaterials and designs for the new generation of face masks have been discussed. Special attention was given to the face masks based on electrospun nanofiber-based membrane materials due to their nano-sized pores, light weight, and high filtration efficiency; therefore, they are commercially viable and popular among various products available in the market. Incorporation of metal organic framework (MOFs) and graphene have opened avenues to more advanced/multi-functional, reusable, and high capacity adsorption filtration membranes. Rapid prototyping/3-dimensional (3-D) printing techniques have been applied to shorten the time of manufacture of face masks. This review is expected to be very helpful for engineers, scientists, and entrepreneurs working on development of novel face masks required in plenty during this pandemic period.

“…As we reviewed very recently, MOFs have been attractive in improving performances of air filters in PM removal and there are three main research targets: (i) increasing the performances in a large quantity; (ii) perfect removal of PMs from air (for example, for a high-efficiency particulate air filter, H13 for >99.995% removal); and (iii) understanding the basics, like mechanism, of PM removal with MOFs. Although there are several results on PM removal with MOFs to increase the performances or to perfectly remove PMs from air, there is little result on understanding the basics of PM removal with MOFs . A few important parameters like charge separation (with polar functional groups), , high porosity, voidage, special structure, − and open metal site/defect − of MOFs have been suggested as the reason to increase their performances in PM removal.…”

Removal of particulate matter (PM) like PM2.5 and PM10 from air was carried out with cotton coated with metal–organic frameworks (MOFs) having various pore sizes to understand the effect of the pore size of MOFs (here, ZIF-8s) on the performances in PM elimination. Both removal efficiency and quality factor, based on the unit surface area of ZIF-8s, in the filtration of PMs with ZIF-8/cotton did not rely considerably on the pore size of ZIF-8s. More importantly, small pores (even less than 0.5 nm) of conventional MOFs like ZIF-8 are more than enough in the elimination of large PMs like PM10 with a size of microns probably because small active sites (such as polar functional groups) on PMs can interact with porous materials having polarity. Additionally, electrostatic interactions between PMs and porous materials could be confirmed as a plausible mechanism for PM removal with ZIF-8/cotton.
