Embodiment 1

[0041] The preparation roadmap of the magnetic porous carbon material of the present embodiment is as follows figure 1 It should be noted that the shapes of the structure-oriented template ZIF-67, core-shell composites, and polymer shells in this roadmap do not represent their actual morphology, and the shapes in the figure are only used to more directly understand The preparation process of magnetic porous carbon materials is described.

[0042] (1) Add 1g ZIF-67, 40mg Pd(PPh 3 ) 2 Cl 2 And 10.6mg CuI, vacuumize, backfill with nitrogen, under nitrogen protection, add 50mL triethylamine and 20mL tetrahydrofuran, stir vigorously at room temperature for 1h; then add 2,7-diiodo-9-(ferrocenevinyl)-9H -Fluorene (3mmol) and tris(4-ethynylphenyl)amine (2mmol) were added to the reaction flask, stirred and dissolved, heated to 90°C and refluxed for 24h; The filter cake was washed with acetone, methanol, and 1,2-dichloroethane to obtain the core-shell composite material ZIF-67@polym...

Abstract

A magnetic porou carbon material and preparation method thereof are disclosed. That method comprise the following steps of: under an inert atmosphere, a structure guide template, a catalyst is dispersed to an acid binding agent and an organic solvent, and the mixture is stirred by 1: 3h, adding ferrocenyl dihalogenated monome and alkynyl monomer, stirring for 24-72h at the temperature of 60-100 DEG C,, purify to obtain that core-shell composite material; The core-shell composites were dispersed in organic acids and stirred for 10-30 min, purify to obtain polymer shell; In an inert atmosphere,pyrolyzing the polymer shell to obtain magnetic porous carbon material at 500-700 DEG C; The ferrocenyldihalogenated monomer is shown in the description, wherein X is Br or I; The alkynyl monomer is shown in the description. The preparation method can control the specific surface area of the material by changing the structure of the monomer to control the pore size of the polymer. The magnetic porous material has large specific surface area and excellent adsorption performance for organic pollutants. Magnetism is good and phase separation does not occur, so the material recycling rate can be improved by magnetic recovery.

Description

technical field [0001] The invention relates to the technical field of carbon material preparation, in particular to a magnetic porous carbon material and a preparation method thereof. Background technique [0002] With the massive discharge of modern industrial and agricultural waste water and domestic sewage, the pollution of the water environment is becoming more and more serious. Among them, the pollution of heavy metals and refractory organic substances (such as polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and aromatic nitro compounds) has become a major issue in my country's water environment. The focus of attention on pollution prevention. [0003] Porous carbon materials have a large specific surface area and have a large adsorption capacity for heavy metals and organic pollutants, but they are often difficult to separate and recycle after adsorption and removal of pollutants, which is likely to cause waste of resources and secondary pollution. The ma...
