KIT-6
Product Detail
KIT-6 is a mesoporous silica molecular sieve (SiO2, CAS No. 7631-86-9) with a bicontinuous cubic mesostructure of Ia3d symmetry and an interpenetrating cylindrical pore system. ACS Material KIT-6 is prepared by the hydrothermal method and supplied calcined and ready to use, with a BET surface area of 600–800 m²/g, a BJH adsorption average pore width of 6.2 nm, comparative crystallinity ≥ 90% and a particle size of 10–100 µm.
Mesoporous silica nanoparticles from ACS Material are synthesized via the hydrothermal method, resulting in a material that demonstrates high thermal and mechanical stability. Mesoporous silicas are particularly effective as molecular sieves with potential applications in medicine, thermal energy storage, biosensing, and imaging. Pore size, particle size, and wall thickness of KIT-6 are tunable.
