Abstract

The invention discloses a preparation method of a novel nanopore organic framework solid alkali material synthesized in one step by heating with a simple solvent. Pore diameter of the material prepared by the method is 5-30nm, pore volume is 0.3-1.44cm3 / g, specific surface area is 300-700m2 / g, and preparation and application field of the material can be further expanded by adjusting preparation conditions. The preparation method is simple and effective, so that a functional nanoporous divinyl benzene material with rich mesoporous structure can be synthesized in one step; imidazole or pyridineis taken as an alkali center, so that the problem that existing alkaline materials are poor in carbon dioxide adsorption performance is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a novel nanoporous organic framework solid alkali material. Background technique [0002] With the rapid development of global industry, while people's material life has been greatly improved, the resulting environmental problems have also become difficult problems faced by the whole world. Among various environmental problems, the greenhouse effect caused by the excessive emission of carbon dioxide directly affects the change of the global climate, and this problem has also attracted widespread attention worldwide. In my country, relevant emission standards and legislative regulations have been established for carbon dioxide emissions, and the establishment of low-carbon and environmentally friendly cities has been highly valued. [0003] In order to effectively reduce excessive carbon dioxide in the air, it is the most effective way to selectively adsorb carbon d...
