Property under strongly acidic conditions (reaction solution initial pH value down to 2), it is thin to be successfully prepared NiAl-HTLcs on aluminum substrates
Film, concurrently houghite growth is relatively slow under acid condition now, and the size of crystallization is smaller, is tightly combined with substrate, no
It is easy to fall off.
In recent ten years, porous anodic alumina template is received significant attention as effective template of preparation nano material.
It has regular three-dimensional open-framework, good chemical stability and thermal stability, higher hardness and biggish specific surface area.
It can be not only aluminized hydrotalcite film if using porous anodic alumina template for the growth substrate of hydrotalcite film
Growth provides silicon source abundant, can also be class by regulating and controlling its aperture and duct state, such as orifice throat length, pore wall thickness
The growth of hydrotalcite provides more spaces, and hydrotalcite film is made to be created on the outer surface and hole of porous anodic alumina template
In road (inner surface), three-dimension film is formed.How rationally to control reaction condition or assisted using instrument, makes houghite crystal
Equably growing simultaneously in the surfaces externally and internally of porous anodic alumina template is the key that realize three-dimensional hydrotalcite film preparation
Problem.
Yang etc. is reported in Mater.Lett.2008,68:1302-1304 uses hexa for precipitating reagent,
It is successfully prepared zinc-aluminum gavite film on the outer surface of porous anodic alumina template, but in template duct and zinc is not present
Aluminium houghite crystal.Ding etc. is reported in Mater.Lett.2012,77:1-3 will be dissolved with metal nitrate and hexa-methylene
The mixed solution of tetramine flows through the solution after heating by circulation after molecular sieve filtration after 90 DEG C of heating, with constant flow pump porous
Anodic oxidation aluminium formwork, the NiAl-HTLcs that can be prepared in porous anodic aluminium oxide surfaces externally and internally dense growth are thin
Film, the hydrotalcite film of other compositions fail preparation, are to reach its under instrument auxiliary diffusion to prepare purpose.
Analyze the above result of study discovery: for the substrate with cellular structure, since houghite crystal is in weakly acidic pH
Or formed and grown fastly under alkaline condition, the blocking of porous anodic aluminium oxide substrate opening of the channel is easily caused, is caused on inner surface
It is difficult to form houghite crystal；Diffusion method is assisted using instrument, can realize certain houghite crystal by forced circulation
In the nucleation and growth of inner surface.Up to the present, other easier methods be yet there are no and realize three-dimensional hydrotalcite film
The report of preparation.
Summary of the invention
