Problems solved by technology

Traditional amino-functionalized ordered mesoporous materials are mostly synthesized in the following two ways: the first is to graft amino groups onto them by post-treatment, that is, to synthesize ordered mesoporous materials first, and then through nitration or ammonia gas treatment. Amino groups are connected, but this synthesis method is tedious, the order degree of ordered mesoporous materials is low, the cost is very high, and the nitrogen source utilization rate is low, harmful to the environment, and the industrialization feasibility is low; the second method uses phenol and metaspores. Aminophenol and other nitrogen sources are co-doped and synthesized by polymerization, but in this method, the amino group will react with the carbonyl group to form a Schiff base, which will affect the degree of cross-linking polymerization. Therefore, the nitrogen content of the ordered mesoporous material obtained by this method very low

The amino-functionalization ordered mesopore phenolic resin material has a two dimensional hexagonal ordered mesopore structure, is high in degree of order, large in specific area, rich in active amino sites, and has wide application prospect in fields of organic alkali catalytic reaction, CO2 adsorption and heavy metal ion adsorption, and the like.

Description

technical field [0001] The invention relates to a phenolic resin material, in particular to an amino functionalized ordered mesoporous phenolic resin material and a preparation method thereof. Background technique [0002] Amino-functionalized ordered mesoporous phenolic resin polymer materials play an important role in the fields of energy storage and conversion, catalysis, adsorption and separation due to their special structure and surface properties. The pore size of ordered mesoporous polymers is 2-50nm, the pore size is uniform, and the pores are arranged in an orderly manner, which is a hot topic emerging in recent years. Traditional amino-functionalized ordered mesoporous materials are mostly synthesized in the following two ways: the first is to graft amino groups onto them by post-treatment, that is, to synthesize ordered mesoporous materials first, and then through nitration or ammonia gas treatment. Amino groups are connected, but this synthesis method is tediou...
