Description
Technical field
The present invention relates to technical field of inorganic nano-material preparation, the preparation side of nanometer sodalite under specially a kind of low temperature
Method.
Background technique
Sodalite is a kind of porous silicoaluminate zeolite with small-bore, its aluminum-oxygen tetrahedron and oxygen-octahedron phase
Interconnection structure can fill small molecule, non-stoichiometric salt at the three-dimensional framework with cube hole (referred to as SOD cage), in cage
Class and metal " cluster ".Since it is with unique space structure and physicochemical properties, sodalite is used as hydrogen storage extensively
Material, photochromic material and adsorbent.
Nanometer sodalite has the characteristics that molecule is easy to diffusion and large specific surface area and is closed since its crystallite dimension is small
Note has bigger application value in terms of adsorbing with hydrogen storage.In recent years, the researchers conjunction to nanometer sodalite always
At being explored, have some pertinent literature reports.Ma Yingchong etc. (Chemical Journal of Chinese Universities, 2006,27:739~741) with
1- ethyl-3-methylimidazole bromide ([emim] Br) ionic liquid is solvent, is made crystal grain about 200~500nm's under normal pressure
Sodalite crystal, research think that solvent or template different in system causes the difference of zeolite crystal growth environment, lead to shape
At crystal morphology it is different.On this basis, Zang Lijun etc. (2013,32 (3): 220~223) adopt by Dalian Polytechnic University's journal
With the mode of microwave heating, the sodalite nano powder of high-crystallinity, narrow particle size distribution is synthesized under the open ionic liquid system of normal pressure
Body, average grain diameter are only 20nm or so.This method is compared with the ionothermal synthesis of conventional heating, and the dosage of ionic liquid reduces
20%, crystallization time shortens 90%, reduces costs, improves combined coefficient.Both methods is required with ionic liquid
As crystallization medium, cost is too high, it is therefore necessary to find other more effective experimental methods.Yang little Yue etc. (science and technology with
2015,15 (20): engineering 249~251) under normal-pressure open system, is taken water as a solvent, is synthesized in the way of microwave heating
Crystallinity is high, partial size 30nm or so nanometer sodalite.The method greatly reduces the cost that ionothermal synthesis uses ionic liquid.
Ji Yuanyuan etc. (CN201510347496.4) reports one kind without condition existing for any organic additive and structure directing agent
Under, the method for preparing nanoscale sodalite.This method is synthesized using two steps, by the alkaline mixed serum of silicon-aluminum containing 40~100
DEG C 2~10h of crystallization, then in 70~200 DEG C of 1~5h of aging, sodalite crystalline form obtained is having a size of 200~800nm.Jiang Yang etc.
A kind of method that (CN 201510021734.2) reports low temperature controlledly synthesis SOD type sodalite, it is molten that this method prepares mixing first
Then liquid clay mineral is added in mixed solution under agitation, stir 0.5~4h, it is anti-that mixture is sealed in hydro-thermal
Answer in kettle 12~36h of hydro-thermal reaction under the conditions of 60~120 DEG C.The sodalite of this method preparation is by diameter close to 2um, thickness
For the stereochemical structure that the round sheet crystal of 30~50nm assembles, these round sheet crystal have common center (former
Point), they are mutually inlayed centered on origin is staggeredly assembled into frame structure.
In conclusion the method for existing synthesis nanometer sodalite mainly has hydrothermal synthesis method, ionothermal synthesis etc., but close
At method there are still higher cost, preparation process is complicated the disadvantages of.Therefore, it is necessary to find it is a kind of at low cost, quickly and easily
Nanometer sodalite synthetic method.
