There is a need to develop highly selective and efficient materials for capturing uranium (normally as UO2(2+)) from nuclear waste seawater. We demonstrate the promising adsorption performance of S(x)-LDH composites (LDH Mg/Al layered double hydroxide, [S(x)](2-) polysulfide with x = 2, 4) uranyl ions variety aqueous solutions including report high removal capacities (q(m) 330 mg/g), large K(d)(U) values (10(4)-10(6) mL/g at 1-300 ppm U concentration), % removals (>95% 1-100 ppm, or ∼80% ppb...

Herein, we report a significantly improved thermoelectric figure of merit ZT ∼1.1 at ∼923 K in p-type SnTe through In2Te3 alloying and iodine doping. We propose that the introduction indium Sn sites creates resonant levels inside valence bands, thereby considerably increasing Seebeck coefficients power factors low-to-middle temperature range. Unlike SnTe–InTe, SnTe–In2Te3 system displays much lower lattice thermal conductivity. Utilizing model for point defect scattering, analyze origin low...
Intercalation of polysulfides into LDHs forms layered composites that can separate Hg<sup>2+</sup>, Ag<sup>+</sup> and Cu<sup>2+</sup> from mixed ions with high selectivity capacity.
We demonstrate strong iodine (I2) vapor adsorption using Mg/Al layered double hydroxide (MgAl-LDH) nanocomposites intercalated with polysulfide (Sx2–) groups (Sx-LDH, x = 2, 4, 6). The as-prepared LDH/polysulfide hybrid materials display highly efficient capture resulting from the reducing property of polysulfides. During adsorption, I2 molecules are reduced to I3– anions by [Sx]2– that simultaneously oxidized form S8. In addition chemical additional molecular is physically captured LDH...
We report detailed studies showing that the novel layered polysulfide compounds Sx-LDH (Sx2–, polysulfides, x = 2, 4, 5; LDH, Mg–Al double hydroxides) can capture efficiently large quantities of mercury (Hg0) vapor. During adsorption process, interlayer polysulfides [Sx]2– react with Hg0 through their S–S bond to produce HgS. The structure before and after Hg-adsorption was characterized X-ray diffraction, vibration spectroscopy, scanning electron microscopy. presence adsorbed Hg verified by...
