Mesostructured porous silica

It has ordered and large pores with diameter in the range 1.5-10 nm and specific surface area of 1500 m 2 /g. Mesoporous silica materials with different pore volumes were functionalized by wet impregnation with a variety of amines for the purpose of CO 2 adsorption. The effects of the concentration and composition of amine blends, silica supports, and adsorption temperature on CO 2 adsorption were investigated. Mesostructured silica tubes and rods were prepared by deposition of a prehydrolysed silica sol with surfactant onto the cylindrical pores of a polycarbonate (PC) membrane template, followed by calcination to remove the surfactant and membrane template.

59 Nanoparticles with thin metal shells (typically gold) around silica core can absorb or scatter light over a wide spectral range. 60, 61 Such particles have applications in imaging and anticancer therapy. However, by removing the organic template a porous inorganic material is received. 1.1.1 Inorganic matrix The inorganic matrix in the mesostructured materials can be varied. Most commonly used are SiO2 (silica) and TiO2 (titanium dioxide), but also other types of metal oxides have been used such as aluminium, tungsten, iron and zirconium oxide.

The role of the co-structure directing agent in the formation of

The preponderance of these materials is made by sol–gel processing wherein soluble silica precursors are reacted to form amorphous networks composed of siloxane bonds. We report that transparent mesostructured silica/gold nanocomposite materials with an interpore distance of 4.1 nm, as-synthesized from a templated sol–gel synthesis method using discotic trinuclear gold(I) pyrazolate complex, were successfully utilized for the fabrication of thin film mesoporous silica nanocomposites containing gold nanoparticles. Self‐standing films of surfactant mesostructured materials have been prepared with vinyltrimethoxysilane (VTMOS) as a silica source. The transparent films, obtained by the co‐condensation of VTMOS This indicates that the integration of mesostructured silica containing an organic ligand into a porous alumina membrane is useful for developing a membrane-based analytical chip. Porous silica material with palladium clusters embedded inside is an example of a potential material for hydrogen storage.
