Description

A kind of stratiform carbon electrode material and preparation method thereof
Technical field
The present invention relates to a kind of stratiform carbon electrode materials and preparation method thereof.
Background technique
Hydrotalcite is a kind of new inorganic material with layer structure, the metal composite oxide roasted at 500 DEG C It can restore the layer structure of hydrotalcite in water, unique memory effect and adsorption capacity make it in synthesizing new material side There is huge application potential in face.Currently, the carbon electrode in battery does not have special construction typically, so to novel The exploration of carbon electrode is always in progress.
Summary of the invention
The present invention proposes a kind of stratiform carbon electrode material and preparation method thereof, uses calcine-recovering method, utilizes hydrotalcite Phenol resin oligomer is embedded into its interlayer by the memory characteristic of product of roasting, is formd and orderly phenolic resin undershoot layer Structure finally obtains the carbon material of stratiform after being carbonized, for making electrode.
The technical scheme of the present invention is realized as follows:
A kind of stratiform carbon electrode material, using hydrotalcite as raw material, then using its product of roasting bimetal composite oxide as mould Plate makes it that can revert to the layer structure of hydrotalcite, to the phenolic aldehyde of insertion hydrotalcite molecule interlayer using its uniqueness memory characteristic Resin oligomers are constrained, so that phenolic resin forms stratiform arrangement architecture in interlayer, it is final after being carbonized to it Obtain the carbon electrode material with layer structure.
Preferably, the hydrotalcite is Mg-Al hydrotalcite, and product of roasting bimetal composite oxide is Mg-Al LDO。
Preferably, the Mg-Al hydrotalcite has layer structure, and product of roasting Mg-Al LDO has memory characteristic, It can restore the layer structure of Mg-Al hydrotalcite in water.
A kind of stratiform carbon electrode material and preparation method thereof, comprising the following steps: by Mg-Al hydrotalcite at 500 DEG C The Mg-Al LDO obtained after roasting restores layer structure in water, then by the phenol resin oligomer to be alkalized with NaOH not Stop being added with stirring wherein, continues to be stirred to react 24 hours, filtering drying obtains phenol resin oligomer intercalated houghite； The product after drying is placed at 100 DEG C again and carries out high polymeric, phenolic resin high polymer intercalated houghite is obtained, in N2Atmosphere It is carbonized under protection, then is removed hydrotalcite shell with 2mol/L HCl, it is final to obtain the carbon electrode material with layer structure Material.
The present invention is the beneficial effects are as follows: the present invention pollute few in the production process, and method is simple, quickly while can It is prepared on a large scale, provides a practicable approach for synthesizing new carbon material electrode.
Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with the embodiment of the present invention, it is clear that retouched The embodiment stated is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, originally Field those of ordinary skill every other embodiment obtained without making creative work, belongs to the present invention The range of protection.
Embodiment:
Mg-Al hydrotalcite (Mg-Al LDHs) is put into Muffle furnace, roasts 6 hours, is cooled to room temperature at 500 DEG C Afterwards, it weighs 60g product of roasting Mg-Al LDO to be added in the large beaker of 1000ml, the distilled water that 300ml is added makes it restore stratiform Then structure measures phenol resin oligomer 100ml (32g/100g) and carries out basification, is then added in the case where keeping stirring In large beaker, continue to be stirred to react 24 hours, filtration washing is dried at 40 DEG C after for several times, obtains phenol resin oligomer intercalation Hydrotalcite.Product after drying, which is placed at 100 DEG C, carries out high polymeric, phenolic resin high polymer intercalated houghite is obtained, in N2 It is carbonized within calcination 6 hours at 500 DEG C under atmosphere protection with tube furnace, then with 170ml 2mol/L HCl by hydrotalcite shell Removal, it is final to obtain the powdered carbon electrode material with layer structure.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
