“…Figure 1 showed the XRD spectra of Fe and Cu ratios of 1:0, 3:1, 1:1, 1:3, and 0:1, respectively. For the diffraction peak of Cu-free doped catalyst, the value of the obvious peak is consistent with the diffraction peak of MIL-101 (Fe) previously reported [ 35 ]. When Cu is added into the catalyst, the ratio of Fe to Cu becomes 3:1.…”

In this work, the combination of high surface area diatomite with Fe and Cu bimetallic MOF material catalysts (Fe0.25Cu0.75(BDC)@DE) were synthesized by traditional solvothermal method, and exhibited efficient degradation performance to tetracycline hydrochloride (TC). The degradation results showed: Within 120 min, about 93% of TC was degraded under the optimal conditions. From the physical–chemical characterization, it can be seen that Fe and Cu play crucial roles in the reduction of Fe3+ because of their synergistic effect. The synergistic effect can not only increase the generation of hydroxyl radicals (•OH), but also improve the degradation efficiency of TC. The Lewis acid property of Cu achieved the pH range of reaction system has been expanded, and it made the material degrade well under both neutral and acidic conditions. Loading into diatomite can reduce agglomeration and metal ion leaching, thus the novel catalysts exhibited low metal ion leaching. This catalyst has good structural stability, and less loss of performance after five reaction cycles, and the degradation efficiency of the material still reached 81.8%. High performance liquid chromatography–mass spectrometry was used to analyze the degradation intermediates of TC, it provided a deep insight of the mechanism and degradation pathway of TC by bimetallic MOFs. This allows us to gain a deeper understanding of the catalytic mechanism and degradation pathway of TC degradation by bimetallic MOFS catalysts. This work has not only achieved important progress in developing high-performance catalysts for TC degradation, but has also provided useful information for the development of MOF-based catalysts for rapid environmental remediation.

“…Morphologies and Structures of the Samples. As seen in the XRD patterns (Figure 1(a)), the MIL-101(Fe) composites exhibit the diffraction peaks located at 2θ = 2 7°, 5.0°, 8.9°, 9.5°, 10.6°, and 16.3°were observed, which was resembled with the existing researches [19]. This indicated that the synthesized powder is high-purity crystal.…”

Sponge-like porous Fe2O3 nanomaterials were obtained through the calcination process of the iron-based metal organic framework (MIL-101). As anode materials for lithium-ion batteries, thus, obtained products show a good electrochemical performance with a high specific capacity (1358 mA h g-1 at 100 mA g-1 in the initial cycle) and a relatively stable cycle performance (750 mA h g-1 after 80 charge/discharge cycles). The superior cycling performance may be attributed to their special structure, which facilitates charge transfer and Li+ diffusion.

“…The photocatalytic degradation in the presence of PS and HP was carried out in the real wastewater matrix to approximate the artificial results to the real condition. Indeed, the real wastewater comprised of different kinds of inorganic and organic compounds that compete to react with the reactive oxygen species [58]. As it is stated in the literature, the available impurities in the real wastewater quench the active oxidizing radicals which in turn cause the lower degradation performance [59].…”

In this work, the cubic cobalt and zinc doped and co-doped magnetite nanocatalysts were synthesized and characterized using different analysis. The so-synthesized photocatalysts were used for the activation of hydrogen peroxide (HP) and persulfate (PS) under UVA irradiation. The integration of Fe 2.5 Co 0.3 Zn 0.2 O 4 improved the activation of PS and HP; wherein, the UVA/Fe 2.5 Co 0.3 Zn 0.2 O 4 /PS process demonstrated higher degradation performance for Sulfalene (SFL) as a veterinary pharmaceutical contaminant in water. Afterward, the effect of different physicochemical parameters was studied and the radicals generated through the process were identified using chemical scavengers. UVA/Fe 2.5 Co 0.3 Zn 0.2 O 4 /PS process brought about 67% of SFL degradation in real wastewater. Moreover, 85% of TOC removal was achieved within 15 h of the abovementioned process. Eventually, the phototoxicity of the untreated and treated SFL solution after 120 min of the UVA/Fe 2.5 Co 0.3 Zn 0.2 O 4 /PS process was studied using Lemna minor aquatic species.
