Mo S Intercalated Layered Double Hydroxide: Highly Selective Removal of Heavy Metals and Simultaneous Reduction of Ag Ions to Metallic Ag Ribbons.

We demonstrate a new material by intercalating Mo S into Mg/Al layered double hydroxide (abbr. Mo S -LDH), exhibiting excellent capture capability for toxic Hg and noble metal silver (Ag). The as-prepared Mo S -LDH displays ultra-high selectivity of Ag , Hg and Cu in the presence of various competitive ions, with the order of Ag >Hg >Cu >Pb ≥Co , Ni , Zn , Cd .

Highly efficient capture of uranium from seawater by layered double hydroxide composite with benzamidoxime.

Through swelling/restoration reaction, benzamidoxime (BAO) is introduced into MgAl-LDH interlayers to assemble a new composite of MgAl-BAO-LDH (abbr. BAO-LDH). Wet samples of the BAO-LDH obtained by washing with diverse solvents are present in colloidal state, which facilitates the fabrication of thin film adsorbents convenient for actual application.

SDC/OS-LDH composite for highly sensitive fluorescence detection of Fe at a much lower concentration.

In this work, we demonstrate the tunable luminescence of newly synthesized SDC/OS Mg/Al-LDH composites (SDC is 4,4'-stilbenedicarboxylic acid; OS is 1-octanesulfonic acid sodium; LDH is layered double hydroxide) and their application in fluorescence sensing to detect Fe(iii) ions. Through an ion-exchange method, the SDC and OS anions with changed molar ratios are intercalated into the LDH interlayers to obtain composites of SDCOS-LDH (x = 0.02, 0.

Polypyrrole-MoS: An Efficient Sorbent for the Capture of Hg and Highly Selective Extraction of Ag over Cu.

The new material Polypyrrole-MoS ( MoS-Ppy) is a new material prepared by ion-exchange between Ppy-NO and (NH)MoS. The MoS-Ppy was designed to exhibit strong selectivity for Ag and highly toxic Hg in mixtures with other ions. It displays an apparent selectivity ranking of Hg > Ag ≥ Co, Ni, Cu, Zn, Cd, and Pb.

Hierarchical microsphere assembled by nanoplates embedded with MoS and (NiFe)S nanoparticles as low-cost electrocatalyst for hydrogen evolution reaction.

The development of low-cost electrocatalysts with high performance is important to provide sustainable hydrogen energy. In this work, via one-step sulfuration of [Formula: see text] intercalated NiFe-layered double hydroxide (abbr. NiFe-MoO-LDH), hierarchical microspheres are assembled by intersecting nanoplates (15-30 nm in thickness) which are then decorated with MoS and (NiFe)S nanoparticles (∼25 nm in size).

Hierarchical Nanoassembly of MoS/CoS/NiS/Ni as a Highly Efficient Electrocatalyst for Overall Water Splitting in a Wide pH Range.

The design of low-cost yet high-efficiency electrocatalysts for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) over a wide pH range is highly challenging. We now report a hierarchical co-assembly of interacting MoS and CoS nanosheets attached on NiS nanorod arrays which are supported on nickel foam (NF). This tiered structure endows high performance toward HER and OER over a very broad pH range.

Layered rare-earth hydroxide (LRH, R = Tb, Y) composites with fluorescein: delamination, tunable luminescence and application in chemosensoring for detecting Fe(iii) ions.

We demonstrate a novel example of tunable luminescence and the application of the delaminated FLN/OS-LRH composites (LRHs are layered rare-earth hydroxides, R = Tb, Y; FLN is the fluorescein named 2-(6-hydroxy-3-oxo-(3H)-xanthen-9-yl)benzoic acid; OS is the anionic surfactant 1-octane sulfonic acid sodium) in detecting Fe(iii) ions. The FLNxOS1-x species (x = 0.02, 0.
