Amino functionalized mesoporous macromolecular small nanosphere and preparation method thereof

Abstract

The invention discloses an amino functionalized mesoporous macromolecular small nanosphere and a preparation method thereof. The small nanosphere is a spherical particle with diameter of 100-200 nm, and has a three-dimensional centered cubic phase mesoporous structure. The preparation method comprises the following steps: taking p-nitrophenol, formaldehyde and phenol as raw materials; synthesizing a nitro functionalized high-molecular performed polymer by a hydrothermal method; then conducting a hydro-thermal treatment on the high-molecular performed polymer at 120-130 DEG C for 16-24 h; then cooling to room temperature; separating out solids in the mixed reactants; and calcining the solids in a protective atmosphere at 350-380 DEG C to obtain a target product. The amino functionalized mesoporous polymer small nanosphere provided by the invention has the advantages of high amino content, large specific surface area, 3D centered cubic phase mesoporous structure, stereoscopic morphology, simple and controllable preparation process and low cost, and has wide application prospects in the fields of organic base catalytic reactions, CO2 adsorption and heavy metal ion adsorption.

Description

Technical field [0001] The present invention involves a medium -hole polymer nano -material and its preparation process, and specially involves one amino -functional meritorized hyperton nano -small ball and its preparation method. Background technique [0002] Traditional media materials have many advantages, and have been widely used in the fields of catalytic, adsorption, and energy storage.However, most of the traditional media materials are made of solvent volatilization and induced self -assembly method (EISA). The production rate of its preparation process is low, the workload is large, and the materials are macro -disorderly, have irregular appearances and long -hole roadsThese factors will lead to unfavorable quality and diffusion, which will severely restrict the application of traditional media materials in the field of catalytic and adsorption. Invention content [0003] The main purpose of the present invention is to provide an amino -functional medium -to -hole pol...

Problems solved by technology

However, traditional mesoporous materials are mostly prepared by solvent evaporation-induced self-assembly method (EISA), which has low yield and heavy workload, and the prepared materials are macroscopically disordered, with irregular morphology and long channels. , these factors will lead to unfavorable mass transfer and diffusion, which will seriously restrict the application of traditional mesoporous materials in the fields of catalysis and adsorption.
