Aperture material

Aperture material
Mesoporous materials refer to a class of porous materials having a pore size between 2 and 50 nm. Mesoporous materials have extremely high specific surface area, regular ordered pore structure, narrow pore size distribution, and continuously adjustable pore size, which make it adsorb and separate macromolecules that are difficult to complete in many microporous zeolite molecular sieves, especially in the catalytic reaction. Although there are many techniques for analyzing pore-related properties, X-ray diffraction has a non-destructive advantage, and this makes it an ideal means of characterizing mesoporous materials.
