Assembly Chemistry of Anion-intercalated Layered Materials

Inorganic nanolayers: structure, preparation, and biomedical applications

“…The octahedral holes of the O-H alternate planes are occupied by Mg 2+ ions, accounting for the triangular lattice similar to the one occupied by O-H ions, resulting in neutral layer. [10][11][12][13][14] The structure of brucite is shown in Figure 2.…”

Modification of Three Types of Bentonite with Zirconium Oxide Chloride (ZOC) of Local Products Using Intercalation Process

“…Then Mg + transfer into WP for those three of bentonites were insignificant, but for the most significant Ca + transfer was gained at bentonite 3 up to 0.45%. With the greater elements transfer of Na + and Ca 2+ from SP into WP, this matter proved that both the two elements were the most role playing at the intercalation process in the lining of inter layer LDHs of pore radius by using DVR methods bentonite [18].…”

“…, Fe 3+ and Zn 2+ metals Layered double hydroxides (LDHs) released which were replaced by Zr was an indicator of the intercalation successful [17][18]. The following were observation results of alkali and alkaline earth metals released in the water phase (WP) compared to the solids phase (SP) during the intercalation process Zr with three types of bentonite, whereas the observation was made by using the atomic absorption methods.…”

“…According to Sun [19], intercalation the existence of chloride ion in the hydroxide matrix would bound intercalant cation at the ionic binding based. The removal of which using water would be very effective due to the existence of very strong hydrogen binding between the water molecules for removing the chloride ions [18].…”

Mössbauer, XRD and TEM Study on the Intercalation and the Release of Drugs in/from Layered Double Hydroxides

“…The most often applied method is the co-precipitation of the component salts with the help of a base in solution. [4] LDHs can be represented by the general formula of [M 2+ 1−xM 3+ x(OH)2(A n-)x/n] · yH2O, where M 2+ is a divalent N cation, M 3+ is a trivalent cation, A n-is an interlayer anion with charge n and x and y are fraction constants. [5] The metal cations occupy the centres of edge-shared octahedra, whose vertices contain hydroxide ions connected to form infinite two-dimensional sheets ( Figure 1).…”
