Description
Technical Field
The invention relates to the technical field of environment function adsorption materials, in particular to a three-dimensional porous graphene aerogel material and a preparation method and application thereof.
Background
Since the industrial revolution, with the increasing frequency of human activities, the concentration of carbon dioxide in the atmosphere has been increasing. CO 22As an important member of greenhouse gases, the increase in their concentration causes global warming, which in turn destroys the ecological environment. Therefore, how to effectively capture CO in the atmosphere2Is a concern for people all over the world. In the capture of CO in a plurality of2Among the methods, the adsorption method has been paid attention by researchers because of its advantages such as low cost, wide adsorption temperature range, low regeneration energy consumption, etc.
The important point to be considered in the adsorption method is the selection of the adsorbent, and the solid amine adsorbent becomes a research hotspot in the field of carbon dioxide capture due to the advantages of high adsorption capacity, high adsorption rate, high selectivity and the like. At present, a solid amine adsorbent using a porous material as a carrier has been extensively studied, and the porous material mainly includes carbon materials, metal organic framework Materials (MOFs), zeolite base, and the like. Among them, graphene has excellent mechanical properties and a large specific surface area (2600 m theoretically)2The,/g), good mass transfer and heat transfer capabilities, etc. have attracted a great deal of researchers. However, graphene is a two-dimensional material that is easily stacked during use, limiting its specific surface area. In addition, graphene alone has a low capacity for carbon dioxide adsorption at low pressure because it lacks a pore structure and is not loaded with basic compounds (e.g., amines). The three-dimensional porous graphene aerogel has a hierarchical pore structure and comprises micropores, mesopores and macropores. In addition, the pore channel has larger size and small mass transfer resistance, and is an ideal solid amine adsorption material.

And then, under the alkaline environment and the oxygen condition, polymerizing dopamine on the surface of the graphene oxide to obtain the graphene oxide/polydopamine composite aerogel. The organic amine reagent used in the method is dopamine, and the content of amino groups in dopamine molecules is low, so that the active adsorption sites of the composite aerogel are few, and the adsorption effect of the composite aerogel applied to carbon dioxide is poor (the adsorption quantity is only 1.02mmol/g through experimental tests). In addition, the interaction force between dopamine molecules and graphene oxide is weak, graphene oxide lamella cannot be crosslinked in the form of chemical bonds, the structural stability is poor, and the effect in the carbon dioxide adsorption regeneration process is poor (the regeneration efficiency is low).
