Specific embodiment
Three-dimensional porous Graphene and preparation method thereof is carried out further below in conjunction with specific embodiment and accompanying drawing
Explanation.
Fig. 1 is referred to, the preparation method of the three-dimensional porous Graphene of an embodiment is comprised the following steps:
Step S10, the solution of ion-exchange type resin and transition-containing metal ion is carried out ion exchange obtain containing transition
Metal ion exchanged type resin.
Wherein in an embodiment, ion-exchange type resin specifically cation exchange resin mainly includes benzene
Ethene system and acrylic acid series this two big series, additionally, ion-exchange type resin can be to be made up of other organic monomers polymerizations, such as
Phenolic aldehyde system, epoxy, vinylpyridine system and ureaformaldehyde system etc..Wherein in an embodiment, the particle diameter of ion-exchange type resin
For 1~5cm, ion-exchange type cross-linkage of resin is 80~90%.
In the solution of transition-containing metal ion, transition metal ions is selected from the iron ion, nickel ion and cobalt with catalytic property
At least one in ion.Resin can obtain grapheme material by heating under the catalytic action of transition metal.Contain transition
The anions of metal ion are selected from SO4 2-、SiO3 2-、PO4 3-、CO3 2-、SO3 2-、S2O3 2-、S2-、Cl-、Br-、I-、NO3 -、
NO2 -In at least one, it is believed that as long as the anion in solution can be formed with transition metal ions water-soluble strong
Electrolytic salt.The concentration of the solution of transition-containing metal ion is 0.01mol/L~10mol/L, specifically, Ke Yishi
0.1mol/L~10mol/L.
When the solution of ion-exchange type resin and transition-containing metal ion is carried out ion exchange, ion-exchange type resin with
The quality CEC of the solution of transition-containing metal ion<4.50mmol/g.Under this condition, ion-exchange reactions can be with
Fully carry out.Specifically, ion-exchange type resin is placed in exchange column, then keeps certain flow velocity to lead to in ion exchange column
Enter transition-containing metal ion solution, the reaction condition for carrying out ion-exchange reactions is:The pH of transition-containing metal ion solution be 0~
14;Maximum operation (service) temperature:Hydrogen≤100 DEG C, sodium form≤120 DEG C;Transition expansion rate %:(Na+→H+)≤10;Work is exchanged to be held
Amount:>=1000mmol/l (wet);The height of ion-exchange reactions exchange column:50cm;Time:About 30 minutes;Operation flow velocity:10
M/h~45 ms/h.
Step S20, transition-containing metal ion crossover resin is dried process.
Wherein in an embodiment, it is which is dried in vacuum to transition-containing metal ion crossover resin dried process
Dry in case.Vacuum is less than 0.1~0.5 atmospheric pressure, and the temperature of drying and processing is 60 DEG C~150 DEG C, drying and processing when
Between be 3~24 hours, time of specific drying and processing is 12~24 hours.In another embodiment, to containing transition
Metal ion exchanged type resin dried process may be used also
So that using drying naturally or infrared drying, during using infrared drying, penetration power is strong, rate of drying
Hurry up.
Step S30, by drying after transition-containing metal ion crossover resin and solid base be mixed to get mixture.
Wherein in an embodiment, at least one of the solid base in NaOH and potassium hydroxide.Contain transition
Metal ion exchanged type resin is 1 with the volume ratio of solid base:4~1:10.By transition-containing metal ion crossover resin with solid
State alkali is mixed the churned mechanically mode that mainly adopt so that both are sufficiently mixed uniformly.
Step S40, mixture is carried out heating by intermittent microwave heating obtain carbide resin.
Wherein in an embodiment, when alternate microwave heating is carried out to mixture, mixture is put into first first
In container, mixture is not more than 80% in the ratio of the first vessel volume;First container has protection cap, can be located at first
On container, play a part of sealing and starvation, protection mixture is not oxidized.First container is positioned over second container
