Preparation method and application of nitrogen-doped porous carbon-loaded cobalt catalyst

[0021] A preparation method of nitrogen-doped porous carbon-supported cobalt catalyst, the steps are as follows:

[0022] Three parts of 100mg N,N-disalicylaldehyde ethylenediamine cobalt(II) were added into respective crucibles, and then placed in a tube furnace, under the hydrogen-argon mixture gas atmosphere with the volume ratio of argon to hydrogen at 95:5 , heating and heating to 600°C, 700°C, and 800°C for calcination, the heating rate is 5° / min, and the calcination time is 1h; after the reaction is completed, cool to room temperature to prepare nitrogen-doped porous carbon-supported cobalt catalysts, which are named respectively It is CoN-C-600, CoN-C-700 and CoN-C-800 nanocomposite catalysts.

[0023] The XRD of CoN-C-600, CoN-C-700 and CoN-C-800 nanocomposite catalyst prepared by this embodiment are as follows: figure 1 As shown, where 2θ is equal to 26° is the diffraction peak of carbon, and the remaining three peaks are the diffraction peaks of simple cobalt. As ...
