 Silicate mesoporous materials are a type of material with unique properties that make them attractive for various applications. These materials are composed of silica and other elements such as alumina, titanium, iron oxide, and magnesia. They have a high surface area and narrow pore size distribution which makes them ideal for applications such as catalysis, separation, selective absorption, and confining guest molecules. Additionally, they can be tailored during synthesis by varying the reactants used, the nature of the surfactant molecule, the auxiliary chemicals, the reaction conditions, or through post-synthesis functionalization techniques.
