preparation example Construction
[0029] In the present invention, the raw material for preparing graphene is preferably biomass carbon source. In the present invention, the preparation method of described graphene preferably comprises the following steps:
[0030] 1), under the action of a catalyst, the biomass carbon source is subjected to catalytic treatment to obtain a first intermediate product, and the catalyst includes one or more of manganese chloride salts, iron compounds, cobalt compounds and nickel compounds Several;
[0031] 2) Under the condition of protective gas, the first intermediate product is heated from the first temperature to the second temperature and then kept warm to obtain the second intermediate product, the first temperature is 20°C-40°C, the The second temperature is 300°C-400°C;
[0032] 3) Under the condition of protective gas, heating the second intermediate product from the second temperature to a third temperature and then keeping it warm to obtain a third intermediate produ...
Embodiment 1
[0063] At 90° C., hydrolyzing corncobs in sulfuric acid for 10 minutes to obtain lignocellulose, the mass of the sulfuric acid being 3% of the mass of the corncobs;
[0064] At 70°C, the lignocellulose was subjected to acidic sulfite treatment for 1 hour to obtain porous cellulose, the pH value in the acidic sulfite treatment process was 1, the acid was sulfuric acid, and sulfite It is magnesium sulfite, the quality of the sulfuric acid is 4% of the quality of the lignocellulose, and the liquid-solid ratio is 2:1.
[0065] The obtained porous cellulose is bleached with hydrogen peroxide, the mass of the hydrogen peroxide is 5% of the mass of the porous cellulose, the bleaching temperature of the hydrogen peroxide bleaching is 100° C., and the bleaching time is 5 hours.
[0066] Stir the porous cellulose and manganese chloride at 20°C for 2 hours for catalytic treatment, the mass ratio of the manganese chloride and porous cellulose is 0.01:1; Drying at a low temperature to obt...
Embodiment 2
[0070] According to the method disclosed by the Chinese patent application number 200810113596.0, graphene is prepared, and the specific process is:
[0071] The silicon substrate is washed with deionized water, ethanol, and acetone in sequence, and then dried, and a layer of zinc sulfide with a thickness of 100 nanometers is deposited on the surface of the silicon substrate by vapor deposition technology as a catalyst;
[0072] The silicon substrate deposited with zinc sulfide is placed in the middle of a clean quartz tube, and the quartz tube is put into an electric furnace so that the middle part of the quartz tube is located in the central area of the electric furnace, and then 100 sccm of hydrogen and 100 sccm of hydrogen are introduced into the quartz tube. After 60 minutes of argon gas mixture, start heating;
[0073] When the temperature in the central area of the electric furnace is as high as 850°C, ethanol is introduced into the electric furnace as a carbon sour...
