Layered Double Hydroxides (LDHs): An Efficient Catalyst System for the Synthesis of Chiral Aminonitriles
Strecker reaction is one of the simplest multicomponent reactions. It used for synthesis of chiral α-amino nitriles. This reaction was carried out in the presence of catalytic amount of layered double hydroxides (LDHs). In this study, simple and practical method for the synthesis of this class of catalysts is provided. The results shown that LDH is the good heterogen catalyst for synthesis of c...
متن کاملANION EXCHANGE REACTIONS OF LAYERED DOUBLE HYDROXIDES (LDHs) AND LAYERED HYDROXY SALTS (LHSs): QUANTIFICATION OF ION EXCHANGE Abstract Anion exchange reactions of a number of layered double hydroxides with inorganic anions
Anion exchange reactions of a number of layered double hydroxides with inorganic anions were investigated. The five LDH systems used in this study were Mg-Al, Ni-Al, Co-Al, Zn-Al and Zn-Cr. Ni-Zn hydroxynitrate and Ni-Zn hydroxyacetate were the LHSs used in this work. In general, all the LDHs and nickel zinc hydroxysalts exhibited higher extent of exchange towards chloride ions. The extent of e...
متن کاملLayered Double Hydroxides (LDHs): Versatile and Powerful Hosts for Different Applications
Layered double hydroxides (LDHs), also known as anionic clays or hydrotalcite-like materials, are a large family of 2D materials constituted by positively charged sheets of hydroxides intercalated by negatively charged anions. In general, the hydrotalcite structures are very robust, with a wide range of possible compositions and so with easily tunable functional properties. In fact, the most ap...

متن کاملSorption of MS2 bacteriophage to layered double hydroxides: effects of reaction time, pH, and competing anions.
Batch sorption and column breakthrough studies were conducted to investigate the potential of layered double hydroxides (LDHs) to remove bacteriophage MS2 from contaminated waters. All four of the LDHs evaluated in this study had very high retention capacities for MS2. Sorption results showed that MS2 could be completely removed from 5.2 x 10(2) plaque-forming units (pfu)/mL solution by Mg-Al L...
