Higher order silicate structure synthesis

With respect to applications, there will certainly be more and more investigations where ordered mesoporous materials are used as catalysts or catalyst supports. However, the more skeptical note of the section on catalysis shall be repeated here In many cases, much cheaper and simpler alternatives exist, and the properties of ordered mesoporous materials are not so much superior to justify the higher effort of their synthesis. On a longer time scale, non-siliceous compositions will probably be used more frequently in catalysis. If one analyzes the catalytic processes implemented today, the majority is not based on silica as catalyst or support, and the single most important area of aluminumsilicates, acid catalysis by zeolites, seems to be less attractive for ordered mesoporous aluminumsilicates, unless a crystallization of the walls to zeolitic structures or the assembly of such materials from colloidal zeolites to enhance the acid strenght becomes possible.
