Title: 3D Cationic Polymeric Network Nanotrap for Efficient Collection of Perrhenate Anion from Wastewater
Abstract Rhenium is one of the most valuable elements found in nature, and its capture and recycle are highly desirable for resource recovery. However, the effective and efficient collection of this material from industrial waste remains quite challenging. Herein, a tetraphenylmethane‐based cationic polymeric network (CPN‐tpm) nanotrap is designed, synthesized, and evaluated for ReO4−recovery. 3D building units are used to construct imidazolium salt‐based polymers with positive charges, which yields a record maximum uptake capacity of 1133 mg g−1for ReO4−collection as well as fast kinetics ReO4−uptake. The sorption equilibrium is reached within 20 min and akdvalue of 8.5 × 105mL g−1is obtained. The sorption capacity of CPN‐tpm remains stable over a wide range of pH values and the removal efficiency exceeds 60% for pH levels below 2. Moreover, CPN‐tpm exhibits good recyclability for at least five cycles of the sorption–desorption process. This work provides a new route for constructing a kind of new high‐performance polymeric material for rhenium recovery and rhenium‐contained industrial wastewater treatment.  more » « less

    The sorption properties of [Zr 6 O 4 (OH) 4 (NH 3 + -BDC) 6 ]Cl 6 · x H 2 O ( MOR-1 ) and H 16 [Zr 6 O 16 (H 2 PATP) 4 ]Cl 8 · x H 2 O ( MOR-2 ) towards ReO 4 − and TcO 4 − were studied in detail. Both MOR-1 and MOR-2 are very effective sorbents for ReO 4 − and TcO 4 − anions, with MOR-2 showing the highest sorption capacity (up to 4.1 ± 0.4 mmol g −1 ) among the known metal organic materials. Importantly, the exceptional sorption capacity of MOR-2 is retained even under conditions simulating acidic nuclear waste. In addition, MOR-1 and MOR-2 exhibit selective luminescence ReO 4 − sensing properties, demonstrated for the first time for MOF materials.

    Poly(pyridinium salts) (PPSs) with positive charges on the backbones were designed and synthesized from the transformation of bispyrylium salts. Such materials exhibited good uptake capacity for rhenium capture from water, and excellent selectivity of ReO 4 − from competing anions. Furthermore, the advantages of facile synthesis and large-scale preparation make this material promising for practical use in industry.

    Abstract Isoreticular chemistry is among the most powerful strategies for designing novel materials with optimizable pore geometry and properties. Of great significance to the further advance of isoreticular chemistry is the development of broadly applicable new concepts capable of guiding and systematizing the ligand‐family expansion as well as establishing correlations between dissimilar and seemingly uncorrelated ligands for better predictive synthetic design and more insightful structure and property analysis. Here ligand circuit concept is proposed and its use has been demonstrated for the synthesis of a family of highly stable, high‐performance pore‐space‐partitioned materials based on an acyclic ligand,trans,trans‐muconic acid. This work represents a key step toward developing highly porous and highly stable pore‐space‐partitioned materials from acyclic ligands. The new materials exhibit excellent sorption properties such as high uptake capacity for CO2(81.3 cm3 g−1) and C2H2(165.4 cm3 g−1) by CPM‐7.3a‐NiV. CPM‐7.3a‐CoV shows C2H6‐selective C2H6/C2H4separation properties and its high uptakes for C2H4(134.0 cm3 g−1) and C2H6(148.0 cm3 g−1) at 1 bar and 298 K contribute to the separation potential of 1.35 mmol g−1. The multi‐cycle breakthrough experiment confirms the promising separation performance for C2H2/CO2.

    Abstract Currently, few porous vanadium metal‐organic frameworks (V‐MOFs) are known and even fewer are obtainable as single crystals, resulting in limited information on their structures and properties. Here this work demonstrates remarkable promise of V‐MOFs by presenting an extensible family of V‐MOFs with tailorable pore geometry and properties. The synthesis leverages inter‐modular synergy on a tri‐modular pore‐partitioned platform. New V‐MOFs show a broad range of structural features and sorption properties suitable for gas storage and separation applications for C2H2/CO2, C2H6/C2H4, and C3H8/C3H6. Thec/aratio of the hexagonal cell, a measure of pore shape, is tunable from 0.612 to 1.258. Other tunable properties include pore size from 5.0 to 10.9 Å and surface area from 820 to 2964 m2g−1. With C2H2/CO2selectivity from 3.3 to 11 and high uptake capacity for C2H2from 65.2 to 182 cm3g−1(298K, 1 bar), an efficient separation is confirmed by breakthrough experiments. The near‐record high uptake for C2H6(166.8 cm3g−1) contributes to the promise for C2H6‐selective separation of C2H6/C2H4. The multi‐module pore expansion enables transition from C3H6‐selective to more desirable C3H8‐selective separation with extraordinarily high C3H8uptake (254.9 cm3g−1) and high separation potential (1.25 mmol g−1) for C3H8/C3H6(50:50 v/v) mixture.

    Abstract Radioactive pertechnetate (TcO4−) from the nuclear fuel cycle presents a severe risk to the environment due to its large solubility in water and non‐complexing nature. By utilizing the chaotropic properties of TcO4−and its nonradioactive surrogate perrhenate (ReO4−) and the principle of chaotropic interactions, a series of quaternary ammonium‐containing polyelectrolyte brush‐grafted silica particles are designed and applied to remove ReO4−from water. These cationic hairy particles (HPs) are synthesized by surface‐initiated atom transfer radical polymerization of 2‐(N,N‐dimethylamino)ethyl methacrylate and subsequent quaternization with various halogen compounds. Dynamic light scattering (DLS) studies showed that the HPs with sufficiently longN‐alkyl andN‐benzyl substituents underwent sharp size reduction transitions in water when titrated with a KReO4solution, indicating strong chaotropic interactions between the brushes and ReO4−. All the HPs exhibited fast adsorption kinetics; the HPs with longerN‐alkyl andN‐benzyl substituents showed higher capabilities of removing ReO4−than those with shorterN‐alkyls. Moreover, the brush particles with longerN‐substituents displayed a significantly stronger ability in selective adsorption of ReO4−than the particles with shorterN‐substituents in the presence of competing anions, such as F−, Cl−, NO3−, and SO42−. This work opens a new avenue to design high‐performance adsorbent materials for TcO4−and ReO4−.
