Background technique
In recent years, supercapacitor is due to having the characteristics that fast charging and discharging, high specific capacitance, safety and environmental protection, part Replace existing rechargeable battery, is used in the fields such as mobile electronic product and electric car.Supercapacitor is considered as It is most suitable for the energy system for making gap between low energy densities capacitor and low power density lithium ion battery up, still, Compared with battery, it need to be improved in energy output facet.
Metal organic framework (Metal-Organic Frameworks, MOFs) material is a kind of using organic ligand and golden Belong to interionic coordination and pass through the porous material with periodical mesh skeleton structure being self-assembly of, it is considered to be is super The potential electrode of grade capacitor.But the electric conductivity of most of original MOFs is very poor, limits its answering in electrochemical field With.In order to improve their electric conductivity, MOFs is usually pyrolyzed into carbon (being no longer MOF) or multiple with conductive material (carbon black) It closes, however, the use of conductive additive can reduce the effective ratio area of MOF.Then, if there is researcher to propose huge ratio The MOF of surface area can in conjunction with conductive characteristic, then MOF material the application of electrochemical field will obtain it is ground-breaking into Exhibition, the appearance of π-d conjugated conductive MOF just solve the problems, such as this, and transition metal ions provides empty d track, and ligand provides one The big pi bond of a delocalization, forms π-d conjugation, and this structure is conducive to the transmission of ion-electron, therefore conductive energy. Recently, Dinca seminar reports a kind of conductive Ni3(HITP)2(six amino three of HITP=2,3,6,7,10,11- Phenylene) MOFs, it is the coplanar structure of a conjugation by the Ni that four amino is coordinated that the aperture of the MOF material, which is 1.5nm, Ligand has the big pi bond of a delocalization.Powdered product is compressed into tablet form structure, can be used as the electrode of supercapacitor.But Intergranular crystal boundary reduces ion/electronics efficiency of transmission, and then limits the further promotion of performance.And there will be conduction Property π-d conjugation MOFs and other two-dimension nano materials with electro-chemical activity it is compound, be expected to overcome this disadvantage, realize more High capacitor.Meanwhile using the effect of composite material synergy, it can prevent conductive MOFs from heap occurring in charge and discharge process It is folded, and then improve the stability of MOFs.Up to now, the research of π-d conjugated conductive MOFs and 2D Material cladding has not yet to see All reports.
Graphene oxide (Graphene Oxide, GO) is the oxidized derivatives of graphene, have biggish specific surface area, Ultra-thin two-dimensional structure and good mechanical strength.Meanwhile the oxygen-containing functional group of GO provides a large amount of functionalization site. Konstantinov seminar is compound by GO and multi-walled carbon nanotube (MWCNT) progress, constructs GO/MWCNT composite material.It is logical The synergistic function for playing the two is crossed, GO/MWCNT composite material is made to show the energy storage property better than homogenous material.By Currently, it is compound by carrying out GO and MOFs, GO/MOFs composite material is constructed, MOFs electrochemical energy storage Quality Research is enhanced Still it is rarely reported.Based on this, in the present invention, 2DGO is introduced into π-d conjugated conductive Cu-HHTPMOFs by we for the first time, structure GO/Cu-HHTP composite material is built, by playing the synergistic function of the two, realizes that charge and discharge process intermediate ion/electronics has Effect transmission, and then improve the energy storage property of system.
