Preparation method and use of amine-functionalized adsorption material with highly dispersed active sites

A preparation method of an amine-functionalized adsorption material with highly dispersed active sites, comprising following steps:

• (1) placing a graphene aerogel (GA) in a tube furnace, and conducting a thermal reduction treatment to produce a thermally reduced sample;
• (2) placing the thermally reduced sample obtained in the step (1) in a plasma vapor deposition tube, and subjecting the sample to a plasma treatment in different atmospheres under vacuum to produce a carrier;
• and
• (3) drying the carrier obtained in the step (2) overnight for 8 h to 16 h;
• adding a polyamine organic amine and the carrier to a reactor, and heating in a forced air oven at 60° C. to 100° C. for 8 h to 15 h;
• taking a reaction product out, and removing an organic amine adhering to a surface of the reaction product;
• soaking in ethanol for 10 min to 40 min, and drying overnight for 8 h to 16 h in the forced air oven at 60° C. to 100° C. to produce the amine-functionalized adsorption material with highly dispersed active sites.
