Mxene Membrane(Mxene 膜)研究综述
Mxene Membrane Mxene 膜 - These results demonstrated that coating polyelectrolyte (PEI) successfully tuned the surface charge and enhanced the hydrophilicity without scarifying the laminar structure of MXene membrane. [1] Based on operando XRD and ex-situ XPS results, we find that the Ti-OH bonds present on the surface of MXene membrane can effectively trigger the LiPS transformation. [2] These findings can be useful in enhancing the structural properties of MXene membranes for water purification applications. [3] Herein, by using an "oxidation-etching" method, MXene membranes are presented with controllable in-plane pores as interlayer to regulate Li ion transportation and LiPS immobilization. [4] Long-term use of the MXene membrane for treating 10 mg-NO3-N L-1 in water was found to have a high faradic efficiency of 72. [5] Two-dimensional (2D) MXene membranes with high thermal and mechanical stability have shown great promise for water purification and desalination given their low energy consumption and high efficiency. [6] Herein, we introduce a facile and practical methodology involving the fabrication of self-interlocked poly (vinyl alcohol) (PVA) and conductive Ti3C2Tx MXene networks, then combining them to construct a nanostructure-engineered PVA/MXene membrane. [7] However, the applications of MXene membranes are limited by their low water permeability owing to narrow channels and high tortuosity. [8] Flux of the prepared PES-Ni@MXene membrane was 2. [9] Therefore, we designed and prepared hydroxyl-rich titanium carbide MXene materials and filtered them onto a commercial polyvinylidene fluoride substrate membrane to obtain a cracked-earth-like MXene membrane with abundant hydroxyl groups and excellent underwater wettability. [10] We report on the specific properties of O- and OH-terminated Ti3C2Tx nanosheets contributing the permeance of MXene membranes with sorption type selectivity. [11] The interlayer spacing of MXene membrane was shrank from 3. [12] Herein, the Ti3C2Tx (T represents O, OH, and/or F) MXene membrane was obtained by depositing Ti3C2Tx MXene 2D nanosheets carbides onto porous polyvinylidene fluoride (PVDF) membranes by vacuum filtration.

[14]这些结果表明，涂层聚电解质 (PEI) 成功地调节了表面电荷并增强了亲水性，而不会破坏 MXene 膜的层状结构。 [1] 基于操作 XRD 和异位 XPS 结果，我们发现存在于 MXene 膜表面的 Ti-OH 键可以有效地触发 LiPS 转变。 [2] 这些发现可用于增强 MXene 膜在水净化应用中的结构特性。 [3] 在此，通过使用“氧化-蚀刻”方法，MXene 膜具有可控的面内孔作为中间层，以调节锂离子传输和 LiPS 固定。 [4] 发现长期使用 MXene 膜处理水中 10 mg-NO3-N L-1 的法拉第效率高达 72。 [5] 具有高热稳定性和机械稳定性的二维 (2D) MXene 膜因其低能耗和高效率而在水净化和海水淡化方面显示出巨大的前景。 [6] 在此，我们介绍了一种简便实用的方法，该方法涉及制造自联锁聚乙烯醇 (PVA) 和导电 Ti3C2Tx MXene 网络，然后将它们结合起来构建纳米结构工程化的 PVA/MXene 膜。 [7] 然而，MXene 膜的应用受限于通道狭窄和曲折度高导致的低透水性。 [8] 制备的 PES-Ni@MXene 膜的通量为 2。 [9] 因此，我们设计并制备了富含羟基的碳化钛 MXene 材料，并将其过滤到商用聚偏二氟乙烯基材膜上，从而获得了具有丰富羟基和优异水下润湿性的类龟裂 MXene 膜。 [10] 我们报告了 O 和 OH 封端的 Ti3C2Tx 纳米片的特定性质，这些特性有助于 MXene 膜的渗透性和吸附类型选择性。 [11] MXene 膜的层间距从 3 缩小。 [12] 在此，Ti3C2Tx（T 代表 O、OH 和/或 F）MXene 膜是通过真空过滤将 Ti3C2Tx MXene 2D 纳米片碳化物沉积在多孔聚偏二氟乙烯 (PVDF) 膜上而获得的。 [13] 大规模制造 MXene 膜应该更容易且更便宜（ACS Nano 2019，DOI：10.

In the current study, we enhance the selectivity of the 2D MXene membrane by coating the membrane surface with tannic acid (TA)-metal complex layer. [1] Herein, 2D MXene membranes with a large area of up to 575 cm2 are prepared by facile electrophoretic deposition (EPD) within 10 min. [2] This work demonstrates that the self-crosslinking strategy is an efficient approach for improving the size-sieving properties of 2D MXene membranes. [3] The engineering as well as the design of atomically thin 2D MXene membranes developed over the past decade have played a major role in high-throughput separation areas. [4]在目前的研究中，我们通过在膜表面涂上单宁酸 (TA)-金属络合物层来提高 2D MXene 膜的选择性。 [1] 在此，通过简易电泳沉积 (EPD) 在 10 分钟内制备了高达 575 cm2 的大面积 2D MXene 膜。 [2] 这项工作表明，自交联策略是提高 2D MXene 膜尺寸筛分性能的有效方法。 [3] 过去十年开发的原子级薄二维 MXene 膜的工程和设计在高通量分离领域发挥了重要作用。 [4]
