Description
Technical field
The present invention relates to layered double hydroxide preparing technical field, more particularly to a kind of lithium of nitrate anion intercalation
The preparation method of aluminium layered double hydroxide.
Background technology
Layered double hydroxide (abbreviation LDH) is a kind of layer being made up of the laminate and interlayer anion of positively charged
Shape material, because its unique property causes extensive concern.LDH has a larger specific surface area, preferable heat endurance with
And stronger ion-exchange capacity, therefore in catalyst, ceramic precursor, adsorbent, ion-exchanger, light and electroactive material
The field such as material, two-dimensional nano solid reactor, biologically active nanometer composite has a wide range of applications.
According to the species of metal ion of composition laminate and the electric charge of institute's band, LDH is mainly divided to two classes.One kind is with MgAl-LDH
(magnalium laminar double-metal hydroxide) is the hydrotalcite type LDH of representative, and its structure is part divalent metal by trivalent
Metal cation substitutes, and forms the laminate with positive charge, and its formula is expressed as：[M2+ 1–xM3+ x(OH)2]x+(An– x/n)·
yH2O].Another kind of LDH is the laminate being made up of monovalent metal cation and trivalent metal cation, such as LiAl-LDH (lithium aluminium
Layered double hydroxide), composition formula is [LiAl2(OH)6]+(An– 1/n)·yH2O；A represents interlayer anion.Its laminate by
Al(OH)3Octahedral voids in layer are by Li+Filling, obtains positively charged laminate, because Al atomic rules are arranged in Al
(OH)3On layer, the octahedral voids that are made up of it are also regularly arranged, therefore Li atoms are also regular is arranged on laminate.
Usually, the affinity of LDH laminates and interlayer anion is bigger, and interlayer anion is more not easy to be handed over by other anion
Change.Anion is with laminate affinity descending order：CO3 2-、SO4 2-、OH-、F-、Cl-、Br-、NO3 -、I-。CO3 2-To LDHs
Laminate affinity is maximum so that CO3 2-The LDHs of intercalation is difficult to be carbonated and obtain the LDHs of other interlayer anions, and NO3 -
It is weaker with the adhesion of laminate, it is easier to be exchanged, therefore directly nitric acid synthesis root intercalation (i.e. nitrate anion is as interlayer anion)
Lithium aluminium layered double hydroxide (abbreviation NO3- LDH) it is significant.
But one-step synthesis NO3- LDH is extremely difficult, in the prior art, has been reported using coprecipitation, with hydrogen-oxygen
Change sodium is precipitating reagent nitric acid synthesis root intercalation lithium aluminium layered double hydroxide (abbreviation LiAl-NO3- LDH), but the knot of product
Brilliant degree is not high, and the pH value of strict control solution is needed in building-up process, just can guarantee that two kinds of cations while precipitates.This
Outer is the purity for ensureing product, needs, using the deionized water for excluding carbon dioxide, to be passed through N in course of reaction2Gas shielded is simultaneously continuous
Stirring, operating process are complex cumbersome.
