preparation example 1
[0023] Provide a polyacrylonitrile activated carbon fiber cloth, its properties are as follows: cloth weight is 70g / m 2 , warp and weft density is 16 threads / in, BET specific surface area is 1,630m 2 / g, the density is 2.09g / m 3 , the carbon content is 85wt%, and the silver content is 0wt%.
[0024] Under a vacuum environment, the fiber cloth was soaked in a 0.1M silver nitrate aqueous solution (pH 3.8) for 5 hours, so that the silver ions were reduced to silver pieces attached to the fiber cloth. Dry the fiber cloth with the silver nub attached to remove any remaining moisture.
[0025] The dried fibers were placed in a high-temperature furnace with a temperature of 400° C. and filled with nitrogen for 90 minutes, so that the silver pieces were cracked into silver particles dispersed and attached to the fiber cloth.
[0026] The fiber cloth with silver particles is ground, pulverized and sieved to obtain an activated carbon fiber (such as figure 2 As shown, the overall c...
preparation example 2
[0029] In a vacuum environment, the polyacrylonitrile-based activated carbon fiber cloth used in Preparation Example 1 was soaked in a silver nitrate aqueous solution (pH3.8) with a concentration of 0.1M for 5 hours, so that the silver ions were reduced to become attached to the fiber cloth. silver nugget. Dry the fiber cloth with the silver nub attached to remove any remaining moisture.
[0030] The dried fibers were placed in a high-temperature furnace with a temperature of 400° C. and filled with nitrogen for 90 minutes, so that the silver pieces were cracked into silver particles dispersed and attached to the fiber cloth.
[0031] Wash the fiber cloth with silver particles with water at a flow rate of 4.5 liters / min for 120 hours to remove the silver particles not attached to the fiber cloth. Dry the cleaned fiber cloth.
[0032]The dried fiber cloth is ground, pulverized and sieved to obtain an activated carbon fiber loaded with silver particles (the overall structure o...
preparation example 3
[0035] Provide a phenolic activated carbon fiber felt, its properties are as follows: the felt weight is 100g / m 2 、BET specific surface area is 1,420m 2 / g, the density is 2.032g / m 3 , the carbon content is 85wt%, and the silver content is 0wt%.
[0036] Under a vacuum environment, the fiber felt was soaked in a 0.001M silver nitrate aqueous solution (pH6.4) for 5 hours, so that the silver ions were reduced to silver lumps attached to the fiber felt. Dry the fiber mat with the silver block attached to remove any residual moisture from it.
[0037] The dried fiber mat was placed in a high-temperature furnace with a temperature of 400° C. and filled with nitrogen for 90 minutes, so that the silver block was cracked into silver particles dispersed and attached to the fiber mat.
[0038] The fiber mat with silver particles is ground, pulverized and sieved to obtain an activated carbon fiber loaded with silver particles (the overall structure of silver particles and activated ca...
