Abstract

The present invention proposes a kind of method of the carbide of utilization hydrotalcite preparation lamellar structure with MgCl2·6H2O is Mg sources, AlCl3·6H2O is Al sources, prepares hydrotalcite, and the carbide that carbonization treatment obtains lamellar structure is carried out after being polymerized by phenol resin oligomer.Phenol resin oligomer is embedded into its interlayer by the present invention using the memory characteristic of hydrotalcite product of roasting, is formd and orderly phenolic resin undershoot Rotating fields, the final carbon material for obtaining stratiform after carbonization.

Description

A kind of method that utilization hydrotalcite prepares the carbide of lamellar structure
Technical field
A kind of method that the carbide of lamellar structure is prepared the present invention relates to utilization hydrotalcite.
Background technology
Layered di-hydroxyl composite metal oxidate (Layered Double Hydroxide, LDH) is hydrotalcite The general designation of (Hydrotalcite, HT) and houghite compound (Hydrotalcite-Like Compounds, HTLCs), by A series of supramolecular materials of these compound intercalations assembling are referred to as hydrotalcite intercalation material (LDHs).1842 Hochstetter is found that natural hydrotalcite ore deposit from schist ore bed first；Earlier 1900s people are because it is found that LDH is to hydrogen Addition reaction has catalytic action and starts to study its structure；Allmann in 1969 et al. is by determining LDH monocrystalline knots Structure, confirms the layer structure of LDH first；After nineteen nineties, with modern analytical technique and means of testing Extensive use, research of the people to LDHs structures and performance is deepened constantly.
The content of the invention
The present invention proposes a kind of method that utilization hydrotalcite prepares the carbide of lamellar structure, using hydrotalcite product of roasting Memory characteristic, phenol resin oligomer is embedded into its interlayer, form with orderly phenolic resin undershoot Rotating fields, through carbon The final carbon material for obtaining stratiform after change.
A kind of method that utilization hydrotalcite prepares the carbide of lamellar structure, comprises the following steps：
(1) with MgCl2·6H2O is Mg sources, AlCl3·6H2O is Al sources, and Mg sources, the amount of Al sources material are respectively 0.03mol, 0.01mol, are dissolved in wiring solution-forming A in 100ml distilled water；0.068molNaOH is taken again to be dissolved in 400ml distilled water Wiring solution-forming B；
(2) solution A is poured into solution B under being stirred at 500 revs/min, continues to stir 10min then by gained mixture Centrifugation, with the precipitation 2 times obtained by distillation water washing；
(3) gained precipitation is redispersed in 400ml distilled water, 500 revs/min of stirrings form suspension in 30 minutes, so 6 hours are incubated in 100 DEG C of baking ovens afterwards, Mg is obtained6Al2(OH)16Cl2·4H2O, i.e. functionalization magnesium hydroxide hydrotalcite suspension；
(4) the suspension 100ml of gained is taken, 1ml phenol resin oligomers, the lower reaction 24 of stirring is added under agitation Hour, gains are centrifuged, brown precipitate is obtained, then in 40 DEG C of vacuum drying, being then heated to 100 DEG C makes the phenolic resin of addition low Homopolymer polymerization, obtains dark brown solid；
(5) in N2Under gas shielded, 6 hours at 500 DEG C, it is carbonized with tube furnace, obtain black powder as sheet knot The carbide of structure.
What the present invention was produced has the beneficial effect that：Carbon material prepared by the present invention has laminated structure, and its unique structure is fitted For in each field new diseases.
Specific embodiment
Technical scheme 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 embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to the present invention The scope of protection.
A kind of method that utilization hydrotalcite prepares the carbide of lamellar structure, comprises the following steps：
(1) with MgCl2·6H2O is Mg sources, AlCl3·6H2O is Al sources, and Mg sources, the amount of Al sources material are respectively 0.03mol, 0.01mol, are dissolved in wiring solution-forming A in 100ml distilled water；0.068molNaOH is taken again to be dissolved in 400ml distilled water Wiring solution-forming B；
(2) solution A is poured into solution B under being stirred at 500 revs/min, continues to stir 10min then by gained mixture Centrifugation, with the precipitation 2 times obtained by distillation water washing；
(3) gained precipitation is redispersed in 400ml distilled water, 500 revs/min of stirrings form suspension in 30 minutes, so 6 hours are incubated in 100 DEG C of baking ovens afterwards, Mg is obtained6Al2(OH)16Cl2·4H2O, i.e. functionalization magnesium hydroxide hydrotalcite suspension；
(4) the suspension 100ml of gained is taken, 1ml phenol resin oligomers, the lower reaction 24 of stirring is added under agitation Hour, gains are centrifuged, brown precipitate is obtained, then in 40 DEG C of vacuum drying, being then heated to 100 DEG C makes the phenolic resin of addition low Homopolymer polymerization, obtains dark brown solid；
(5) in N2Under gas shielded, 6 hours at 500 DEG C, it is carbonized with tube furnace, obtain black powder as sheet knot The carbide of structure.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
