SBA-15 molecular sieve

Brief Introduction

As a mesoporous molecular sieve, SBA-15 is suitable for the catalytic conversion of some macromolecules and can also be used as a carrier of excellent catalysts because its mesoporous size is adjustable in the range of 4-30nm andits specific surface area is more than 500m2 / g. After calcination, the thermal stability of SBA-15 is higher than 900 ℃,and there are a large number of silicon hydroxyl groups on the inner surface, so it has high thermal and hydrothermalstability. At the same time, it also has stable skeleton structure, easy to modify the inner surface and other characteristics. It is a mesoporous material with great application prospects. It has good application value in catalysis, environment,energy, adsorption and separation, biological nano assembly, light, electricity, magnetism and so on.

The reaction is summarized as below

Typical physical and chemical property

SBA-15 mesoporous silica based molecular sieve has highly ordered hexagonal straight pores, the mesoporous size canbe adjusted from 4nm to 30nm, the pore wall thickness is inthe range of 3.1nm to 6.0nm, the skeleton structure is stable,the wall thickness is easy to be doped.
