abWith a view to reducing estrogens pollution in aqueous environments, montmorillonite/hydrochar (MMT/ HC) with or without modification by KOH via hydrothermal carbonization process (HTC) were applied to remove 17b-estradiol (E2) and 17a-ethynylestradiol (EE2). The characterizations of MMT/HC indicated that MMT had been successfully attached onto HC surface, which could cause an improvement in the stability of the clay nanoparticles. MMT/HC with 1% KOH (MMT/HC-K1) exhibited excellent adsorption) compared to those of other adsorbents; approximately 2-fold higher than that of HC. Moreover, the adsorption capacity maintained a high level over a wide pH range (2-8). The pseudo-second-order model and Freundlich model exhibited prior fitting performance for adsorption of E2 and EE2. The regenerated MMT/HC-K1 retained over 80% of its initial capacity after four cycles. The adsorption mechanism on MMT/HC-K1 could be explained by hydrophobicity, p-p bond, electrostatic interaction and H-bonding interaction. Overall, MMT/HC-K1 synthesis from two low-cost materials, could be considered as a competitive adsorbent for estrogens removal from aqueous environment, considering its high adsorption capacity and regeneration ability.

“…[9][10][11][12] Because of its earth-abundant character and high curie temperature, Fe3O4 stands out as a key partner in composites. 13 After Sugimoto's group reported the preparation of magnetite particles with a narrow size distribution in the early 1980s, 14 monodisperse Fe3O4 nanoparticles have been fabricated by various chemistry-based synthetic methods.

A magnetic metal organic framework (MOF) composite was prepared. The composite was fabricated by incorporation of Fe3O4 nanoparticals with MOF. It was characterized and expected to offer a promising template for molecular immobilization and sensor fabrication because of its ordered structure and satisfying large specific surface area. The resulting composite was used to detect methyl parathion. Electrochemical measurements showed that the multifunctional composite of MOF provided an excellent matrix for the co-adsorption of methyl parathion. Owing to the ordered structure, the large surface area, excellent compatibility and magnetic property of the material, methyl parathion could be separated, accumulated and directly detected in the solution with high sensitivity. The differential pulse voltammetry (DPV) response was proportional to the concentration range from 5.00 × 10 -6 to 5.00 × 10 -3 g L -1 with the detection limit of 3.02 × 10 -6 g L -1 . The experimental results can lead to a widespread use of electrochemical sensors to detect organophosphorous pesticides contaminates and other substances.

“…In addition, MOFs containing Fe or Co ions can produce metal-oxide embedded porous carbon materials because of the high boiling point of the reduced metals [15][16][17][18][19]. Although several groups have reported the synthesis of Fe 2 O 3 -embedded porous carbon materials via the pyrolysis of Fe-based MOFs and their applications [19][20][21], to the best of our knowledge, control of the material property of the resulting composite materials has not yet been reported. In addition, magnetite (c-Fe 2 O 3 ) embedded porous carbon has never prepared using MOF as a precursor.…”

Metal oxide nanoparticle embedded porous carbon composite materials have various uses, including as catalyst supports and adsorbents, because of their good stability and unique porosity. Despite their importance, the synthetic strategies of metal-oxide nanoparticle-embedded porous carbon composites to control their properties have not been widely studied. Here, we present a facile synthesis method for c-Fe 2 O 3 -embedded porous carbon materials via the pyrolysis of Fe-based metal-organic framework (MOF, MIL-100). We found that simple treatment to the starting material (MIL-100) allows control c-Fe 2 O 3 particle size, chemical composition, porosity, and H 2 sorption property of the resulting composite materials. This work presents a synthesis of a series of porous carbon composites from a single MOF by treating further carbon source. This synthetic strategy may provide a clue for synthesis of a variety of composite materials using MOFs for battery electrode and catalyst applications.
