Abstract

Elimination of the heavy metals by using the MoS4-LDH adsorbent.

Fabrication of a Gold-Supported NiAlTi-Layered Double Hydroxide Nanocatalyst for Organic Transformations

“…Therefore, designing heterogeneous nanocatalysts could be a better alternative as they can be separated easily by centrifugation or filtration methods and reused after catalyst washing . Layered double hydroxides (LDHs), also named hydrotalcite-like compounds, are a branch of clay minerals having positively charged octahedral-type brucite-like sheets intercalated with anionic charges and H 2 O molecules. , Because of their properties of high surface area and anion-exchange capacities, LDHs have emerged as eco-friendly materials in the fields of catalysis, drug carriers, adsorption, anion exchange, and precursors for magnetic materials. − As LDHs can be synthesized by economic and simple routes, they have gained considerable attraction in the field of catalytic synthesis of organic compounds.…”

Recent advances in the detection and removal of heavy metal ions using functionalized layered double hydroxides: a review

“…By using MoS 4 2− as the intercalation anion, Rathee et al proposed a NiFeTi-LDH nanosorbent for effective removal of heave metal ions within 10 min. 75 In their work, the responses toward various metal ions were listed as the following order: Ni 2+ < Cu 2+ < Zn 2+ < Fe 3+ < Pb 2+ < Ag + . The maximum adsorption capacities toward Pb 2+ and Ag + were 856 and 653 mg g −1 , respectively.…”

Efficient visible-light-driven reduction of hexavalent chromium catalyzed by conjugated organic species modified hourglass-type phosphomolybdate hybrids

“…With the rapid development of industrialization and urbanization, environmental problems caused by heavy metal pollution become increasingly prominent. [1][2][3][4][5] Among numerous heavy metal pollutants, hexavalent chromium (Cr(VI)) in wastewater from wood preservation, dye production, textile, electroplating, petroleum refining and leather process industries has high carcinogenicity, mutagenicity and teratogenicity, and has gained global attention due to its great harm to the environment and human health. [6][7][8][9][10][11] At present, a common treatment method of Cr(VI) in wastewater is to convert toxic Cr(VI) to less toxic trivalent chromium Cr(III) by means of a variety of techniques including ion exchange, 12 chemical precipitation, 13 membrane separation, 14 biodegradation 15 and photocatalytic technology.…”
