Embodiment 1
[0029] A porous active carbon fiber material includes the following steps:
[0030] 1) Collect indoor cleaning cobweb to remove impurities such as large particles solid and dust;
[0031] 2) Use exfoliating water, 1.0mol / L hydrochloric acid, hydrochloric acid, water -free ethanol ultrasound cleaning for 25min, and then wash it with ultra -pure water three times. Dry it at 60 ° C to less than 5%;
[0032] 3) Drying the dry cobweb under 250 ° C is 1H at low temperature pre -carbonization treatment, and then the high temperature carbonization treatment of 900 ° C is 1H, the porous active carbon fiber.
[0033] The porous active carbon fiber scanning electron microscope (SEM) prepared by this embodiment is figure 1 Show.The electron microscope shows that after the high temperature carbonization, the complete spider fiber structure is retained, and the diameter of the carbon fiber is about 100 to 200nm.
Embodiment 2
[0035] A porous active carbon fiber material includes the following steps:
[0036] 1) Collect indoor cleaning cobweb to remove impurities such as large particles solid and dust;
[0037] 2) Use exfoliating water, 2.0mol / L hydrochloric acid, hydrochloric acid, water -free ethanol ultrasound cleaning for 30 minutes, and then clean it with ultra -pure water three times. Dry it at 60 ° C to less than 5%;
[0038] 3) Treating the low -temperature pre -carbonization treatment of the dry cobweb at 250 ° C. After it naturally cools it to room temperature, it will be with a 3x quality FeCl 3 Or zncl 2 Mix, grind and mix well, and then use 900 ° C high -temperature carbonization to treat 2h porous active carbon fibers.
[0039] The porous active carbon fiber scan electron microscope prepared by this embodiment is figure 2 Show.The electron microscopy shows that high temperature activation treatment does not destroy the result of carbon fiber, but activated treatment has formed many micropo...
Embodiment 3
[0041] A microbial fuel cell catalytic reaction catalyst and its catalytic activity research, including the following steps:
[0042] 1) Use 1.0 μm, 0.5 μm, and 0.03 μm electrode polishing powder to treat the vita electrodes, and then clean it in ultrasound in water -free ethanol and ion water in sequence for 10 minutes, dry at 30 ° C;
[0043] 2) Reading 0.5 μg Examples 2 The carbonized cobweb powder obtained by prepared, add 50 μL of ionic water, 100 μl water -free ethanol, and 2 μlnafion solution to prepare a catalyst research solution;
[0044] 3) Take the 8 μL catalyst research solution and drip to the surface of the dry glass carbon electrode, dry it at 30 ° C, you can be used as a working electrode;
[0045] 4) Put the modified electrode in N 2 O 2 Electrochemical testing is performed in the 0.1mkoh solution, including cyclic voltty scanning, rotating disc electrode linear scanning, and studying prepared carbonized catalytic catalytic performance, stability, and methanolic ...
