End；
2）Black powder is scattered in concentration aqueous hydrochloric acid solution, after centrifugation, solid phase drying is taken, obtains carbon-SiO 2 powder；
3）The mixing of carbon-SiO 2 powder, cobalt salt and distilled water is carried out hydro-thermal reaction, reaction is cooled down after terminating, centrifugation, is obtained
Solid sample；
4）To dry after solid sample deionized water and washes of absolute alcohol, obtain three-dimensional meso-hole carbon-cobaltous silicate.
Step 1 of the present invention）The carbon skeleton of the black powder actually Folium Bambusae script doping silicon dioxide that technique is obtained, by its point
Dissipate after finite concentration hydrochloric acid, other impurity metal ions in material are removed by hydrochloric acid, obtain carbon-SiO 2 powder.
The present invention adopt simplicity method can be with Fast back-projection algorithm, without the need for other template reagent or surfactant, you can
Obtain that pattern is homogeneous, surface stacks uniform three-dimensional meso-hole carbon-cobaltous silicate material.
Further, the concentration that the present invention is used for hydrochloric acid in the concentration aqueous hydrochloric acid solution for disperse black powder is 0.5
～2 mol/L.It is miscellaneous that the aqueous hydrochloric acid solution of this concentration can effectively remove the metal for adulterating in black powder in the short period of time
Matter, and its original biomass skeleton will not be destroyed.If concentration is too low, wherein metal impurities cannot be eliminated；If
Excessive concentration, then can make original carbon skeleton carbonization, destroy its structure.
The mixing quality ratio of the carbon-SiO 2 powder and cobalt salt is 1: 5～10.The mixing ratio can effectively improve cobalt
Salt particle is stacked on the uniformity in carbon-silicon dioxide skeleton, realizes the maximization of material specific surface area, so that material is shown more
Good ratio electric capacity.If carbon-SiO 2 powder excess, stacking of the cobalt salt on carbon skeleton can be caused excessively to disperse heterogeneity；If
Cobalt salt excess, can cause crystal grain cluster.
The mixing quality ratio of the more preferably carbon-SiO 2 powder and cobalt salt is 1: 7.
The temperature conditionss of the hydro-thermal reaction are 150～200 DEG C, and the response time is 12～36 hours.Under the reaction temperature
Crystal grain distribution is uniform, and does not form cluster between granule；Under the response time, crystal development is complete, and crystal size is moderate.In the water
Under heat condition, experimental repeatability and controllability are best.Temperature is too low to cause crystal grain to be difficult to grow, and temperature is too high may to destroy crystalline substance
Body structure.The hydro-thermal time is too short to cause crystal grain too small, and overlong time can then cause crystal defect.
In addition, the present invention also proposes above-mentioned three-dimensional meso-hole carbon-application of the cobaltous silicate in ultracapacitor.
After politef, acetylene black and three-dimensional meso-hole carbon-cobaltous silicate are mixed with isopropanol as solvent, drop coating is to foam
On nickel thin slice, tabletting after drying, prepared electrode of super capacitor.
Due to the mesoporous special construction of the unique three-dimensional of material three-dimensional mesoporous carbon-cobaltous silicate, with higher ratio electric capacity and long
Cycle life, so the electrode of super capacitor that makes is in 3.0 M KOH aqueous solutions, 1.0 A g-1Under electric current density than electric capacity about
For 1600 F g-1.
Further, the mixing quality ratio of the politef, acetylene black and three-dimensional meso-hole carbon-cobaltous silicate be 1: 2～
6: 5～10.Politef stable performance, can be cross-linked to form mutually spatial mesh structure, and acetylene black is used for reinforcing material
Electric conductivity.Under the quality proportioning, obtained electrode material, has highest than electric capacity and best electrochemical stability.If poly-
Tetrafluoroethene is excessive, can affect electric conductivity.
The mixing quality ratio of the more preferably politef, acetylene black and three-dimensional meso-hole carbon-cobaltous silicate is 1: 3: 16.
