“…The adsorption process of Se(IV) on Al/Fe-MOF-2/PAN ENFMs is mainly based on chemical adsorption, accompanied by physical adsorption. The results show that the in situ modification of Al 3+ changes the porosity of Fe-MOF, and the AlOOH formed in the pores is conducive to reducing the diffusion rate of Se(IV) in the adsorption system and increasing the adsorption capacity …”

The emerging pollutant selenium has an immeasurable impact on production and life, and selective adsorption and effective utilization of excessive selenium in water bodies is very challenging. In this paper, nanoscale Al/Fe-MOF was obtained by in situ modification of Fe-MOF by Al 3+ , and Al/Fe-MOF-X/PAN nanofibrous membranes were prepared by combining with electrostatic spinning technology for the selective adsorption and enrichment of Se(IV) in water bodies. The adsorption experiments showed that the Al/Fe-MOF-2/PAN nanofibrous membranes had a high adsorption capacity and good selectivity for Se(IV), and the maximum adsorption capacity was up to 228.5 mg/g. The adsorption capacity of the adsorbent for Se(IV) in the actual water body was 220 mg/g. The five adsorption−desorption cycles demonstrated the multiple uses of the materials. X-ray photoelectron spectroscopy (XPS) confirmed that Se(IV) plays an important role in the anion exchange between the −OH in Se and Al species. This study is expected to shed light on the adsorption, enrichment, and transformation of selenium in real water bodies.

“…This indicated that with increasing pH, the Fe element transformed from a single Fe 3+ to Fe 2+ and Fe 3+ coexisting on the sample surface. The absorption peak of Al 2p appeared at 75.0 eV (Figure b), indicating the presence of the Al–O bond, but the absorption peak was affected by noise due to the low content …”

“…The absorption peak of Al 2p appeared at 75.0 eV (Figure 2b), indicating the presence of the Al−O bond, but the absorption peak was affected by noise due to the low content. 35 In summary, the nucleation process of spherical Al−Fe 3 O 4 crystals can be divided into two steps. First, Fe 3+ in the acid leach solution reacts with OH − to generate rod FeOOH (eq 3.1), and then AlO 2 − (eq 3.2) was formed under the condition of sufficient OH − .…”

In recent years, the development of environmentally friendly solid catalysts derived from sludge for the efficient removal of pollutants from wastewater has triggered widespread attention. Acid mine drainage (AMD) sludge is a waste produced in the process of acid mine wastewater treatment and contains multitudes of valuable metal resources. Hence it provides the original conditions for the synthesis of metal-based Fenton catalysts. In this article, the Fenton-like catalyst Al−Fe 3 O 4 derived from AMD sludge was first synthesized by acid leaching coprecipitation methods, and the relationship among catalyst properties and pH, growth temperature, and growth time during coprecipitation was explored. Transmission electron microscope (TEM)/vibrating sample magnetometer (VSM)/particulate size description analyzer (DLS) results showed that the Al−Fe 3 O 4 catalyst with high purity, large particle size, and strong magnetic properties was obtained under the conditions of pH 10, reaction temperature 60 °C, and growth for 45 min. In addition, the introduction of Al active sites promoted the activation of H 2 O 2 and improved the catalytic activity of Al− Fe 3 O 4 , and the degradation efficiency of tetracycline was up to 93.9% within 60 min, which was 1.94 times that of pure Fe 3 O 4 . Moreover, Al−Fe 3 O 4 exhibited excellent recyclability after four adsorption−desorption cycles. Hence, this study is expected to promote the resource utilization of industrial sludge and provide a new idea for the rapid removal of TC from aqueous solution.

“…Herein, a binary mixture of CO 2 and N 2 containing 10 vol % CO 2 is used to anticipate the CO 2 /N 2 selectivity of the as-prepared materials. Initially, the experimental adsorption data for the single components CO 2 and N 2 were measured in a range of 0–100 kPa at 25 °C, which were then described using the Langmuir–Freundlich model [ 31 – 32 ]. The fitted parameters are given in Supporting Information File 1 , Table S1 with high correlation coefficient values ( R 2 ≥ 0.9998) for all samples.…”

A facile approach was employed to fabricate MIL-100(Fe) materials from Fe2O3 nanoparticles through a conventional hydrothermal reaction without the presence of HF and HNO3. Effects of trimesic acid content in the reaction system on the quality and CO2/N2 separation performance of the as-prepared MIL-100(Fe) samples were investigated. Using 1.80 g of trimesic acid in the reaction system yielded the sample M-100Fe@Fe2O3#1.80, which proved to be the optimal sample. This choice struck a balance between the amount of required trimesic acid and the quality of the resulting material, resulting in a high yield of 81% and an impressive BET surface area of 1365.4 m2·g−1. At 25 °C and 1 bar, M-100Fe@Fe2O3#1.80 showed a CO2 adsorption capacity of 1.10 mmol·g−1 and an IAST-predicted CO2/N2 selectivity of 18, outperforming conventional adsorbents in CO2/N2 separation. Importantly, this route opens a new approach to utilizing Fe2O3-based waste materials from the iron and steel industry in manufacturing Fe-based MIL-100 materials.
