Embodiment 1

[0039] 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 iron slag into the autoclave, then add 1g of 4,4'-biphenyldiamine into the autoclave and mix evenly, and react at a temperature of about 400°C and a pressure of 50MPa. After 6 hours, after the reaction, cooling, filtering, drying, grinding and pulverization, the brown metal porous three-dimensional network structure polymer catalyst material was obtained, the yield was 70%, and its appearance was as follows: figure 1 As shown, the TEM test image is as figure 2 As shown, the polymer structure characterization NMR image is shown in image 3 shown.

Embodiment 2

[0041] 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 1g of 4,4'-biphenyl diacid into the autoclave and mix evenly. , reacted for 5.5 hours, after the reaction, cooled, filtered, dried, and pulverized to obtain a dark brown metal porous three-dimensional network structure polymer catalyst material with a yield of 72%, and its appearance is as follows Figure 4 As shown, the TEM test image is 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

[0043] The catalytic reaction is carried out in a volume of 250mL round bottom flask and quartz tube (length: 90cm diameter: 9mm, wall thickness: 0.9mm), water is high-purity water (volume 100mL), and the metal porous three-dimensional network structure obtained in Example 1 The polymer catalyst material is a catalyst (3g). Carbon dioxide passes through pure water at a speed of 3 bubbles / second. After reacting at a high temperature of about 700°C for 4 hours, the chromatographic analysis of the reaction solution is as follows: Figure 8 and shown in Table 1.

Abstract

The invention discloses a metal porous three-dimensional network structure polymer catalytic material and a preparation method thereof. The metal porous three-dimensional network structure polymer catalytic material is prepared by the following method: after drying the iron slag, grinding it into powder, and mixing it with aromatic The reaction of base diamine or diacid under high temperature and high pressure can be obtained; the preparation method is simple to operate, has wide sources of raw materials, low cost and high product yield, and the prepared metal porous three-dimensional network structure polymer is resistant to carbon dioxide reduction in water medium The reaction of generating small organic molecular compounds has good catalytic activity; the technical scheme of the invention can solve the problems that industrial iron slag cannot be processed and pollutes the environment, and can alleviate the greenhouse effect of carbon dioxide, which is of great significance.

Description

technical field [0001] The invention relates to a polymer catalyst material with a metal porous three-dimensional network structure and a preparation method thereof, belonging to the field of synthesis of new polymer materials. Background technique [0002] Non-ferrous metal smelting slag is the waste slag produced during the smelting process of non-ferrous metals. Non-ferrous metal smelting slag has a large amount, many varieties and complex components. Some smelting slags are piled up in open slag yards for a long time, and through different channels of transfer and transformation, they often cause varying degrees of pollution to the surrounding environment. However, these non-ferrous smelting waste residues contain high content of valuable elements, but it is difficult to recycle them. The hydrometallurgy zinc smelting process in the prior art realizes the direct leaching of zinc sulfide by introducing the technology of atmospheric pressure oxygen-enriched leaching and u...
