“…In order to explore the actual maximum adsorption capacity, adsorption experiments of Hg(II) and Pb(II) are carried out at different concentrations (15–300 mg/L). As shown in Figure a,b, with the increasing concentration of ions, the adsorption capacity of Hg(II) and Pb(II) gradually increases to the maximum .…”

Under the hydrothermal condition, a new type of two-dimensional coordination polymer ([Cd(D-Cam)(3-bpdb)] n , Cd-CP) has been constructed. It is composed of D-(+)-Camphoric-Cd(II) (D-cam-Cd(II)) one-dimensional chain and bridging 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene (3-bpdb) ligands. Cd-CP has a good removal effect for Hg(II) and Pb(II), and the maximum adsorption capacity is 545 and 450 mg/g, respectively. Interestingly, thermodynamic studies have shown that the adsorption processes of Hg(II) and Pb(II) on Cd-CP use completely different thermodynamic mechanisms, in which the adsorption of Hg(II) is due to a strong electrostatic interaction with Cd-CP, while that of Pb(II) is through a weak coordination with Cd-CP. Moreover, Cd-CP has a higher affinity for Hg(II), and when Hg(II) and Pb(II) coexist, Cd-CP preferentially adsorbs Hg(II).

“…Considering the excellent properties of graphene, graphene nanopores generated by electron-or ionbeam lithography show extraordinary application value, such as gas separation, [121] water desalination, [8e,122] and wastewater purification. [123] Garaj et al investigated the usage of graphene nanopores to characterize single molecules of DNA in an ionic solution. They pointed out that during the process that negatively charged DNA molecules are electrophoretically drawn to and driven through a nanopore, the ionic current measured would be reduced or blocked due to insulating molecules in DNA.…”

With specific structures and unique features, biological ion channel proteins play crucial roles in many life processes of living organisms. Inspired by the biological ion channel proteins, researchers have developed a variety of artificial nanochannels to explore the mechanisms of selective ion transport and achieve applications in molecular filters, biosensors, and energy conversion devices. The ion transport behavior in nanochannels is mainly governed by the interaction between ions and the nanochannels interface. Herein, the structures, fabrication methods, and ion transport properties of biomimetic solid-state ion nanochannels are reviewed, with emphasis on the transport performance and mechanism of nanochannels. In addition, the current challenges faced and the future outlooks of these solid-sate ion nanochannels for practical applications are discussed.

“…17 Due to its memory effect, LDO can partially be reconstructed into a layered structure in water, further reducing its practical use. 20 The exfoliation of layered materials, such as LDHs, into single-layer nanosheets has been extensively investigated as a facile technique to enhance their textural properties. There are various reports on development of the exfoliated LDH/LDO for various applications.…”

2,5-Furandicarboxylic acid (FDCA) is a potential biopolymer precursor for polyethylene furanoate production. This study focused on synthesizing FDCA via catalytic oxidation of 5-hydroxymethylfurfural (HMF) over Ru-based catalysts supported on exfoliated MgAl-double oxides (LDO) for the first time in a homogeneous base-free system. Effects of the exfoliation solvent, preparation method, and Ru loading level on the physicochemical and catalytic properties of the resulting catalysts were investigated. The exfoliated LDO-supported Ru catalysts exhibited enhanced textural properties, RuO x dispersion, and basicity, resulting in better catalytic activity (at least 6 times higher FDCA yield) than conventional LDO-supported Ru catalysts in the conversion into FDCA. The Ru-based catalyst supported on an exfoliated LDO/carbon nanocomposite, Ru(3)/ESV-LDC, revealed the nearly complete HMF conversion (99.2%) at an FDCA selectivity of >98%. This was attributed to the synergistic effect derived from good RuO x dispersion, providing a high proportion of lattice oxygen for boosting surface oxygen mobility, and high basicity, in terms of both strength and number of basic sites. Moreover, Ru(3)/ESV-LDC exhibited good reusability without a significant loss of HMF conversion and FDCA yield, suggesting strong chemical robustness of RuO x species and a stable interaction between the active metal and support.
