Embodiment 1
[0043] Dry the iron slag under the drying condition of 350°C for 40 hours until the powder is completely dry, and then grind it so that the particle size of the particles is within the range of 200-300 mesh. Add 20g of the treated heavy iron slag into the autoclave, then add 1g of 4,4'-biphenyldiamine, which was wrongly written before, into the autoclave and mix evenly. Under the high pressure condition of 50MPa, react for 6 hours, after the reaction, cool, filter, dry, grind and pulverize to obtain brown metal porous three-dimensional network structure polymer catalyst material, the yield is 70%, and its appearance is as follows: figure 1 As shown, the TEM test image is shown as figure 2 As shown, the polymer structure characterization NMR image is shown in image 3 shown.
Embodiment 2
[0045] Dry the iron slag under the drying condition of 300°C for 45 hours until the powder is completely dry, and then grind it so that the particle size of the particles is within the range of 200-300 mesh. Add 25g of the treated iron slag into the autoclave, then add 1.5g of 4,4'-biphenyl diacid into the autoclave and mix evenly. , reacted for 5.5 hours, and after the reaction, cooled, filtered, dried, and pulverized to obtain a dark brown metal porous three-dimensional network structure polymer catalytic material with a yield of 72%. Its appearance is as follows: Figure 4 As shown, the TEM test image is shown as Figure 5 As shown, the polymer structure characterization NMR image is shown in Figure 6 Shown; Molecular weight distribution as Figure 7 shown.
Embodiment 3
[0047] The catalytic reaction is carried out in a round-bottomed flask and a quartz tube (long: 90cm, diameter: 9mm, wall thickness: 0.9mm) with a volume of 250mL. The reaction solvent is 100mL of high-purity water, and the metal porous three-dimensional network structure polymerized with the obtained embodiment 1 The catalytic material is a catalyst (2g). Carbon dioxide passes through pure water at a speed of 3 bubbles / second. After reacting at a high temperature of about 700°C for 5 hours, the product is mainly methanol, and the yield is greater than 32%. The chromatogram of the reaction solution Such as Figure 8 shown.
