Sheet silicates consist of regular or irregular sequences of tetrahedral (Si,Al)O4- and octahedral (Al,Mg)(OH)6- layers, with water and various cations between them. They are characterized by very fine-grained crystals and can be identified in DTA curves by their characteristic dehydration behavior.
Differential thermal analysis reveals that they can be separated into regular or irregular sequences of tetrahedral and octahedral packets that are connected with three oxygens by plane networks (Fig. 5).
silica sheet has been widely used in a wide range of industrial applications and consumer products such as paper, plastics, glass and paint. It is a low-cost, lightweight material that can be cut and glued to a variety of surfaces.
In addition, it can be formed into thin sheets for use in insulating devices such as transistors and discs for isolated mounting of electronics components. It is also used in the traditional Japanese Kodo ceremony to burn incense.
Mesoporous silica containing surface amino-functional groups can enhance the adsorption of aqueous metal ions such as zinc and copper ions. Here, we synthesized a novel mesoporous silica sheet with surface amino-functional groups (sheet-NH2) by a dual-templating process using Pluronic P123 and N-palmitoyl-l-alanine as templates.
The prepared sheet-NH2 had a higher adsorption capacity of aqueous zinc and copper ions compared to the MCM-NH2. It also had higher pore diameters, pore volumes and BET surface areas than MCM-NH2, and exhibited a much better metal ion binding capacity than calcined mesoporous silica sheets and silica beads with no porous structures.
