摘要

A new metal-organic framework based on manganous (II) ions and a paddle wheel ligand, H-3[Mn3O3(BTB)] (Mn-BTB, HBTB = 1,3,5-tris(4-carboxyphenyl)benzene acid), was synthesized and structurally characterized. Mn-BTB was formed via self-assembly of one-dimensional (1D) helical chains interconnected through the carboxyl groups of the tripodal ligand HBTB to generate a 3D, extended network with a nanotube-like architecture and aperture size of 18.22 angstrom x 16.40 angstrom. The 2-fold self-interpenetration significantly enhanced the stability of the framework, although it minimized the empty space to some extent. Mn-BTB contains an accessible volume of 3143.6 angstrom(3) with a 47.1% porosity, which allowed the adsorption of large dye molecules. Cationic dyes (methylene blue (MB) and rhodamine B (RhB)) and an anionic dye (methyl orange (MO)) were examined for selective dye adsorption on Mn-BTB. Mn-BTB with an anionic skeleton was beneficial for the selective adsorption of cationic dyes. (C) 2018 Elsevier B.V. All rights reserved.

Shao-zhong Hu, Ting Huang, Nan Zhang, Yan-zhou Lei, Yong Wang

Summary: The discharge of wastewater rich in heavy metals and organic substances leads to ecosystem deterioration, environmental pollution, and food pollution. Metal organic frameworks (MOFs) are highly promising materials for wastewater treatment due to their large specific surface area and pore volume, as well as their structure designability. In this study, a novel adsorbent (PEI@UiO-66-NH2) was synthesized and it exhibited improved chemical stability and increased adsorption sites compared to common UiO-66-NH2. The adsorption behaviors of PEI@UiO-66-NH2 were systematically studied, and it was found that it can reach adsorption equilibrium within 5 minutes for Pb(II) and methyl orange (MO). The theoretical adsorption capacities for Pb(II) and MO were found to be 692.80 mg/g and 497.51 mg/g, respectively. The study also established dynamic theoretical adsorption models, providing guidance for scale-up experiments in wastewater treatment. PEI@UiO-66-NH2 showed excellent performance in recycling Pb(II) and MO, indicating its promising application in removing wastewater contaminants.

Highly efficiency blue emissive from Bi3+ions in zero-dimensional organic bismuth halide for white LED applications

Jun'an Lai, Daofu Wu, Peng He, Kang An, Yijia Wang, Peng Feng, WeiWei Chen, Zixian Wang, Linfeng Guo, Xiaosheng Tang

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Study on the wear resistance and mechanism of AlCrCuFe2NiTix high-entropy surfacing alloys

Xuewei Liang, Yunhai Su, Taisen Yang, Zhiyong Dai, Yingdi Wang, Xingping Yong

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.
