Technical field
The invention belongs to porous inorganic material synthesis field, specifically a kind of macropore material with carbon element preparation method.
Background technology
Classification according to IUPAC, porous material can be divided into three major types: large pore material (direct > 50nm), mesoporous material (2nm��directly��50nm) and poromerics (direct < 2nm). Due to poromerics and mesoporous material Industrial Catalysis with the field such as separate and apply with succeeding, so being always up research and the focus of application. In recent years, compensate for conventional small pore molecular sieve along with large pore material in the field such as bulky molecular catalysis, separation and mesoporous material is difficult to the shortcoming that allows macromole to enter within duct, and the advantage that some other physical chemical characteristics embodies, the sight of the researcher attracted gradually, becomes the popular domain of research.
