Abstract

The invention relates to a porous carbon material based on two-dimensional polymer and preparation method thereof. The preparation method comprises the following steps: mixing the two-dimensional aromatic polymer and pore-forming agent uniformly according to the mass ratio of 1:3-6, then carbonizing in an inert atmosphere at 400-1,000 DEG C, and obtaining porous carbon materials based on the two-dimensional polymer after the reaction. The porous carbon material based on the two-dimensional polymer has hydrophobic property, can physically adsorb CO2 at high temperature (60-90 DEG C), can be recycled at room temperature, and has simple and convenient recycling operation.

Description

technical field

[0001] The invention relates to the field of porous carbon material preparation technology and gas adsorption technology, in particular to a two-dimensional polymer-based porous carbon material and its preparation and application. Background technique

[0002] The emission of carbon dioxide produced by industrial production and human life is increasing year by year. The resulting greenhouse effect triggers global warming, sea level rise, and extinction of animals and plants, which will directly threaten the ecological environment and social economy. Therefore, it is imminent to design and prepare materials with carbon dioxide capture and storage properties. Theoretically, the improvement of carbon dioxide adsorption performance mainly depends on the high specific surface area, large micropore volume and suitable heat of adsorption of the adsorbent. However, simply increasing the specific surface area cannot significantly improve the carbon dioxide adsorption...
