AbstractA new anion exchangeable layered compound with a composition of Ni1-xZn2x(OH)2(OCOCH3)2x·nH2O (0.15 < x < 0.25) was prepared by hydrothermal hydrolysis of Ni-Zn mixed acetate solutions. The structure is related to zinc basic salts such as Zn5(OH)8Cl2·nH2O and Zn5(OH)8Cl2·nH2O; nickel ions form brucite-type hydroxide layers with vacanciesNi1-x(OH)2, and zinc ions occupy the tetrahedral sites above and below the vacant sites outside the hydroxide layers. Acetate ions are weakly bound to the Zn2+ ions, completing the tetrahedra, and easily exchanged with most of inorganic as well as organic anions. The reactions are reversible. Exchange with [Si8O20]8- ions resulted in the formation of two-dimensional silicate layers analogous to those of 2:1 type clay minerals.

Generic Term

Background: The development of new emerging nanomaterials for water treatment has attracted more and more interests recently. MXenes is a generic term for a series of new two-dimensional (2D) transition metal carbides and carbonitrides materials which have graphene-like structure. As a new type of 2D lamellar nanomaterial, many researches have focused on the design and synthesis of MXene-based nanomaterials owing to their large number of inter-layer void with the two-dimensional stacking structure, large specific surface area, rich and adjustable surface functional groups and strong hydrophilicity. On account of their unique properties, related discussion and potential of 2D MXenes nanomaterials for membrane separation and water treatment applications are provided. Objective: The goal of this paper is to review new emerging 2D MXenes nanomaterials for the fabrication of various composite membranes and related applications for water treatment. Method: In this review, the design and synthesis of MXene-based composite membranes for water treatment was extensively discussed. Results: Membrane separation technology is an effective approach for solving water pollution problem due to its low energy consumption, environment friendly and easy operation. MXene-based membranes with different molecular sieving behaviors for small organic molecules and ions and corresponding applications in water purification and desalination were discussed. Conclusion: Although composite membranes constructed by 2D MXenes nanomaterials can be prepared to achieve high water flux and satisfactory rejection, most researches focused on the exploration of membrane formation with multi-layered compound or few-layered MXenes. In the near future, the functional properties of the MXene itself should be paid more attention for development of various novel membranes.

A new porous material was prepared from a layered compound, K4Nb6O17, through the exfoliation of its layers. A composite of the niobate sheets and MgO particles were obtained by precipitating the exfoliated two-dimensional niobate sheets with MgO fine particles. Porous niobium oxide was obtained by removal of the MgO particles from the composite after thermal treatment. It had a large surface area and showed higher photocatalytic activity than the original H+/K4Nb6O17 for H2 evolution from various aqueous alcohol solutions.
