Laminate.The divalent metal M being positioned on laminate2+Can be golden by the close trivalent of ion half price in certain proportion
Belong to cation M3+Same order elements so that laminate is positively charged, interlayer exist can exchange anion and laminate on positive electricity
Lotus balances so that the overall structure of LDHs is electroneutral.The anion of interlayer can be exchanged, through a series of modifications, hydrotalcite
Material can obtain many materials planting different properties.
Content of the invention
It is an object of the invention to as overcoming the deficiency that in prior art, manganese oxide structure is single, provide one to be used for processing useless
The preparation method of the manganese oxide nanometer sheet of gas.
The technical solution used in the present invention is in turn include the following steps:
1) by MnCl2It is dissolved in water, is configured to the solution that concentration is 1～2mol/L, this solution of 500mL is placed in constant temperature
It in 70～80 DEG C of water-baths, is simultaneously added dropwise 30% (mass fraction) hydrogen peroxide 2～4mL and a certain amount of NaOH weak solution, keep pH
Value is 12～13, reacts 2～3h, proceeds in autoclave, be warmed up to 150～180 DEG C in 1h, continues reaction 4～8h, naturally cold
But arriving room temperature, forming the precipitation with layer structure, precipitate and separate in this process, deionization is washed 2～3 times；
2) solid that precipitation obtains is joined in the sodium lactate solution that concentration is 2～4mol/L, solid-to-liquid ratio be 1:10～
1:50, stir 4～5h, precipitate and separate, it is thus achieved that solid after being washed with deionized 2～3 times, the temperature of 400～450 DEG C
The lower calcining of degree, removes lactate therein, i.e. can get a kind of manganese oxide nanometer sheet.
The invention have the advantage that the manganic that part divalent manganesetion is generated by hydrogen peroxide oxidation, divalent ion and generation
Trivalent ion under the effect of alkali, produce co-precipitation, form lamella hydrotalcite structure, then enter lactate at piece Inter layer exchange,
Finally by high-temperature calcination, lactate is removed, form the lamellar structure relatively scattered.This structure is conducive to absorption and catalysis dirt
Dye thing.
