“…As can be seen from Figure 2, the strong diffraction peaks appear in MIL-53(Fe) at 2θ degrees of about 9.4°, 12.6°, 17.8°, 25.4°, and 27.3°. This was similar to the previous literature report [25]. NH2-MIL-53(Fe) showed characteristic diffraction peaks at 2θ degrees of 8.9°, 10.1°, 14.7°, 16.7°, 17.8°, 24.1°, and 25.9°.…”

With the rising incidence of various diseases in China and the constant development of the pharmaceutical industry, there is a growing demand for floxacin-type antibiotics. Due to the large-scale production and high cost of waste treatment, the parent drug and its metabolites constantly enter the water environment through domestic sewage, production wastewater, and other pathways. In recent years, the pollution of the aquatic environment by floxacin has become increasingly serious, making the technology to degrade floxacin in the aquatic environment a research hotspot in the field of environmental science. Metal–organic frameworks (MOFs), as a new type of porous material, have attracted much attention in recent years. In this paper, four photocatalytic materials, MIL-53(Fe), NH2-MIL-53(Fe), MIL-100(Fe), and g-C3N4, were synthesised and applied to the study of the removal of ofloxacin and enrofloxacin. Among them, the MIL-100(Fe) material exhibited the best photocatalytic effect. The degradation efficiency of ofloxacin reached 95.1% after 3 h under visible light, while enrofloxacin was basically completely degraded. The effects of different materials on the visible photocatalytic degradation of the floxacin were investigated. Furthermore, the photocatalytic mechanism of enrofloxacin and ofloxacin was revealed by the use of three trappers (®O2−, h+, and ®OH), demonstrating that the role of ®O2− promoted the degradation effect of the materials under photocatalysis.

“…Among them, flexible MOF materials with respiration, swelling, ligand rotation and interlayer displacement effects show great potential for gas storage, adsorption, separation and catalysis especially (Bukhtiyarova et al, 2007). In order to obtain more effective flexible MOF catalysts, many methods have been proposed to modify them, especially Fe-based MOF MIL-53(Fe), for example organic ligand-doped (Xu et al, 2023) and metal-doped (Zhu et al, 2023), two methods effectively enhance its photocatalytic activity and degradation performance on tetracycline pollutants, respectively. However, there are few studies on the removal of H2S by modified flexible Fe-based MOFs.…”

Deep eutectic solvent (DES) as the guest molecule and flexible Metal-organic framework (MOF) as the supporting material can be used to provide an efficient catalyst: flexible dual Fe-based DES@MOF, which can efficiently remove H2S in discontinuous removal process (100-180°C). The materials were characterized by XRD SEM, FT-IR, BET, XPS, TG, CV and Py-FTIR. According to the result, MOF (MIL-53(Fe)) incorporating 30 wt% DES (ChCl/FeCl3) exhibited the best H2S removal performance at 180°C, with the H2S removal capacity of 2527 mg mL -1 (3744 mg g -1 ). And the H2S removal capacity reduced by 9% after two cycles of thermal regeneration. The process of desulfurization includes two stages: catalytic oxidation and adsorption, which are determined by the Fe 3+ in DES and the structural characteristics, such as the aggregation of mesopores, respectively. For MIL-53(Fe), FeOOH as an intermediate and Lewis acid sites also played a catalytic role. Elemental sulfur was the predominant product with a small amount of sulfate. Both elemental sulfur and DES can induce the flexible deformation of MOF as the guest molecule to relieve the passivation of catalyst.
