Zeolite A and ZK-4,crystals of zeolite A with chamfered edges (average size 3–5 µm), cubic crystals of ZK-4 with sharp edges (average size 1–2 µm), and nano-sized cubic crystals of zeolite A with slightly rounded edges (size ≤ 1 µm).

Mesostructured Silica Thin Films,branes. Solvent evaporation-induced self-assembly methods based on supramolecular organization of amphiphilic molecules in combination with sol-gel processing of condensable inorganic precursors result in porous thin films with a monomodal pore size distribution. These films are typically deposited by spin coating, casting or dip coating.

LURE

Organically Modified Monolithic Silica Aerogels,oxypropyl or 2-aminoethyl-3-aminopropyl groups), followed by supercritical drying with carbon dioxide. The resulting material is characterized by a very low density (0.14–0.27 g·cm.), high porosity and surface areas from 250 to 600 m.·g. depending on the kind of organic moiety used. The organic groups are easily accessible for further reactions.

Montmorillonites with Mixed Aluminum-Lanthanide Oxide Pillars, of tetrahedral aluminum in the pillars. The materials have a high thermal stability, and high specific surface area and porosity, with pores at the limit between micropore and mesopore sizes. The number and strength of the acid sites in these materials is also high.

方便

Birnessite-type Manganese Oxide by Redox Precipitation,nessite is prepared by reacting an aqueous Mn(NO.). solution with a NaOH / H.O. solution at room temperature. A highly crystalline birnessite is obtained by hydrothermal treatment of the poorly crystalline birnessite in a NaOH solution.
