“…For example, Wang et al [19] synthesized Bi-BTC using trimesic acid (H 3 BTC) as the ligand, which exhibited high photocatalytic activity for O 2 production. Kong et al [20] synthesized a Bi-based MOFs material, Bi-TBAPy, using pentafluorobenzoic acid and 2,2-dipyridine as organic ligands, which displayed excellent photocatalytic degradation activity for Congo red, and the degradation efficiency reached 96 % within 20 min. Some researchers have used Ti to construct MOFs for the degradation of organic pollutants [21] ; the most common is MIL-125 (Ti), but the wide band gap of 3.69 eV limits visible light absorption.…”

Removal of organic pollutants from wastewater remains a significant challenge. Hence, we report a series of novel MOFs based BixTiy‐BTC photocatalysts synthesized by hydrothermal method for decontamination of 1,1‐Dimethylhydrazine (UDMH). The preparation parameters of MOFs were optimized, the best catalytic performance was achieved by adjusting the Bi/Ti molar ratio to 1 : 3, with Bi1Ti3‐BTC a photocurrent density of 0.35 mA/cm2 was reached. The morphology and composition of the materials were analyzed, titanium doping increased the specific surface area. Bi1Ti3‐BTC was loaded with magnetic nano‐Fe3O4, which prevented agglomeration of Bi1Ti3‐BTC and increased the specific surface area, thus improving photocatalytic activity. The band gap structure of the semiconductor materials was estimated by UV‐Vis and XPS valence band spectra, while the separation efficiency of photogenerated carriers was investigated by photocurrent density and PL (Photoluminescence) spectrum. The photocatalytic degradation rate of UDMH rapidly decreased after addition of EDTA, indicating that h+ was the main active species in the photocatalytic degradation process. The photocatalytic removal efficiency of UDMH with Bi1Ti3‐BTC/Fe3O4 at a concentration of 0.5 g/L reached 97.58 % after illumination for 180 min, and after 210 min near quantitative degradation was observed.

“…A number of Bi-MOFs have been developed for several purposes, such as gas adsorption (CO 2 , CH 4 ) and photocatalysts, − or general applications. − However, since many MOFs are often based on divalent late first-row transition metals to obtain a low framework density for a gravitational advantage, use of Bi-MOFs for gaseous iodine adsorption has not been actively investigated.…”

In this study, a bismuth-based metal−organic framework (Bi-MOF) was investigated in its applicability as an iodine adsorbent at high temperatures for possible applications under severe accidents in a nuclear power plant. Bi-mna was selected among Bi-MOF candidates based on its thermodynamic characteristics, which expected to allow chemisorption of iodine by bismuth. Its iodine adsorption performance was compared with zeolitic imidazolate framework-8 and Cu-BTC and other MOFs which were chosen due to their diversity in iodine adsorption mechanisms. Bi-mna was synthesized at the laboratory scale, and the aforementioned three MOFs were tested for iodine adsorption at various temperatures from 350 to 600 K. The adsorption mechanism of Bi-mna was investigated by conducting various analyses including thermogravimetric analysis, X-ray diffraction, X-ray photoelectron spectroscopy, and Brunauer−Emmett−Teller. The results showed that Bi-mna has good adsorption performance (700 mg-I/g-adsorbent) while maintaining good thermal stability even at a high temperature (up to 575−600 K). The iodine capture performance of Bi-mna is better, especially at high temperature, in comparison with those of non-MOF adsorbents such as silver-exchanged zeolites and bismuth-embedded SBA-15. Analysis results confirmed that Bi-mna chemically captured iodine by breaking bonds between bismuth and sulfur to form new chemical bonds between iodine and the bismuth in Bi-mna. The results indicate that Bi-mna has the potential to be used in capturing radioiodine at high-temperature environments, such as during nuclear severe accident management. Its use should also be considered as a potential candidate for waste form development.

“…For example, G. Z. Wang synthesized a visible‐light‐responsive bismuth‐based metal‐organic framework (Bi‐mna) (H 2 mna = 2‐mercaptonicotinic acid), which showed good photoelectric and photocatalytic properties. A bismuth‐based fluorine‐containing metal‐organic framework [Bi(OOCC 6 F 5 ) 3 (C 10 H 8 N 2 )(H 2 O) 2 ] (OOCC 6 F 5 = pentafluorobenzoate, C 10 H 8 N 2 = 2,2′‐bipyridine) was prepared by a hydrothermal method, which showed excellent properties of degrading Congo red in the presence of UV/Vis radiation . In addition, the composites Bi 2 WO 6 /UiO‐66 (UiO‐66 = a zirconium based MOF) and BiVO 4 /MIL‐101(Cr) were also synthesized and they exhibited enhanced photocatalytic activity under visible‐light irradiation.…”
