Embodiment 1

[0038] In this example, the preparation process of the high specific surface area carbon composite material based on the in-situ growth of foamed iron is as follows:

[0039] (1) Pretreatment of foamed metal and activated carbon powder: Take several sheets of foamed iron, the number of pores (PPI) is 1 to 1000, dissolve anhydrous sodium carbonate in water to make a certain concentration of lye, and immerse the foamed iron Lye, boil for 40 minutes, take out after degreasing, rinse with clean water. Prepare a dilute acid solution with oxalic acid, soak the degreased foam iron in the dilute acid solution, boil for 30 minutes, take it out, rinse it with clean water, and dry it for later use. After the above degreasing and surface etching, the surface of the foamed iron is clean and uneven. Under the protection of nitrogen, the activated carbon powder is baked at 250-500°C for 1 hour, cleaned with water after cooling, until the cleaning solution is neutral; dried, ground, and siev...

Embodiment 2

[0051] Prepare a multi-dimensional high specific surface area carbon composite material based on in-situ growth of foamed iron and nickel, and load a photocatalyst, which is applied to pollutant treatment and integrated in a photocatalytic system device. The specific implementation steps are as follows:

[0052] (1) According to the preparation method of the multi-dimensional high specific surface area carbon composite material based on the in-situ growth of foamed iron-nickel in Example 1, the high specific surface area composite material based on the in-situ growth of foamed iron-nickel is prepared, the difference is that the foamed The iron is replaced by foamed iron-nickel with a pore count (PPI) of 13.

[0053] (2) Titanium sol is obtained by sol-gel method; the multi-dimensional high specific surface area carbon composite material based on foamed iron-nickel in-situ growth obtained in step (1) is immersed in the sol, taken out after soaking for 30 minutes, and heated at ...

Embodiment 3

[0058] Take the high specific surface area composite material based on the in-situ growth of foamed iron prepared in Example 1, cut it into a suitable size, load a manganese catalyst on it, and under the condition of the presence of ozone, catalytically degrade toluene pollutants at low temperature. For the treatment device, see figure 2 . The specific implementation steps are as follows:

[0059] (1) Take the high-performance carbon composite material based on the in-situ growth of foamed iron prepared in Example 1, and cut it into a suitable size.

[0060] (2) At room temperature of 25°C, dissolve manganese acetate in ethanol to make a saturated solution, immerse the carbon composite material with a good size in the manganese acetate solution for 20 minutes, take it out, and put it under the condition of 80-150°C , dry for 30-120 minutes, after drying, set aside.

[0061] (3) Step (2) The carbon composite material loaded with manganese acetate, under the protection of nit...

Abstract

The invention discloses a carbon composite material based on the in-situ growth of foamed metal and a preparation method thereof. The composite material is produced in situ on the foamed metal, the components of the precursor of the composite material are carbon material, thermosetting resin and Porogenic organic macromolecule polymer, and moreover, the mass proportion of the carbon material, thethermosetting resin and the Porogenic organic macromolecule polymer is 1:0.2-20:0.01-0.3. The preparation method is as the following: (1) the pretreatment of the foamed metal and the carbon material;(2) proportioning; (3) loading; (4) carbonizing and pore forming; and (5) activation of steam. The carbon composite material and the preparation method of the invention are based on the foamed metal,the composite material is provided with an excellent multidimensional spatial reticular structure, and at the same time, the thermosetting resin and the developing resin are adopted as the double efficiency of carbon resource and adhesive. Furthermore, the carbon composite material and the preparation method of the invention utilize the property that the powder of each carbon material have small shrinkage and take the powder of each carbon material as support architecture, thus overcoming the shortages of shrinkage and low porosity of the thermosetting resin in a carbonization process.

Description

technical field [0001] The invention relates to a carbon composite material based on in-situ growth of foamed metal and a preparation method thereof. Background technique [0002] Foam metal as porous metal, also called foam metal. Foamed metal belongs to the multi-dimensional space network structure, with low density and high porosity, and has good structural properties such as the strength and characteristics of metal, and is easy to cut. The permeability of foamed metal makes it have low resistance and low pressure when passing fluid. Therefore, foamed metal can be used as filter material and carrier material etc., is widely used in the production and manufacturing sectors such as chemical industry, petroleum, textile, medicine (CN1451477; Material Engineering, 1998, (12), 43-47: the development of foamed metal , properties and applications (II) - properties and applications of metal foams; Materials Herald, 2007, 21 (Special VIII), 380-383: preparation and application...
