Why is mesoporous important?
Mesoporous materials provide robust templates for the synthesis of nanowires of semiconductors, metals and oxides. It is shown that the use of polyoxide templates as surfactants can allow simple control of mesopore sizes over a very wide range.
Why is mesoporous silica?
Mesoporous silica nanoparticles (MSNs), which are nanometer-sized drug carriers, have been proved to be a versatile delivery vehicle with attractive features such as stability, large surface area, tunable pore sizes and volumes, and easy encapsulation of drugs, proteins, and biogenic molecules.
How do you make MCM 41?
MCM-41 was prepared through a modified conventional synthesis method [35] by adding TEOS to an aqueous solution containing CTAB, 1 M of NaOH, and deionized water. The molar composition of the initial gel mixture was 1.0:0.09:3.57:62.05 TEOS/CTAB/NaOH/H2O.
What are mesoporous materials used for?
Several applications, such as removal of pollutants from water, storage, of gases (e.g., CO2, H2, O2, CH4, H2S), adsorptive xylene separation, and separation of biological and pharmaceutical compounds, have been addressed through the use of mesoporous materials as adsorbents.
What is ZSM-5 What is its formula?
ZSM-5, Zeolite Socony Mobil–5 (framework type MFI from ZSM-5 (five)), is an aluminosilicate zeolite belonging to the pentasil family of zeolites. Its chemical formula is NanAlnSi96–nO192·16H2O (0.
What is the meaning of 5 in ZSM-5?
ZSM-5 is a synthetic zeolite which contains silica (Si) and alumina (Al) with the. ratio of silica greater than the alumina. The catalyst is known as ZSM-5 because it has a pore diameter of 5 Å (angstroms) and it has more than five Si/Al ratios.
Is ZSM-5 A zeolite?
ZSM-5 is a synthetic zeolite which contains silica (Si) and alumina (Al) with the ratio of silica greater than the alumina. The catalyst is known as ZSM-5 because it has a pore diameter of 5 Å (angstroms) and it has more than five Si/Al ratios.
What is a MFI zeolite?
Abstract. High Resolution Image. Silicalite-1 (structure type MFI) is an important zeolite that, in addition to conventional applications such as adsorption and catalysis and emerging applications such as thin films and membranes, is often used as a model system in studies of zeolite crystal growth.
