Abstract

The invention relates to a method for synthesizing SOD type sodalite in a low-temperature controllable manner. The method comprises the following steps: 1) preparing a mixed solution, namely, dissolving strong alkali into deionized water at normal temperature, adding an aluminum salt and a silicon source, and uniformly stirring, thereby obtaining the mixed solution; and 2) synthesizing the SOD type sodalite, namely, under the stirring condition, adding a clay mineral into the mixed solution, stirring for 0.5-4 hours so as to obtain a mixture, sealing the obtained mixture in a hydrothermal reaction kettle for hydrothermal reaction for 12-26 hours at 60-120 DEG C, or adding the obtained mixture into a backflow reaction device to carry out stirring backflow reaction for 18-36 hours at 80-150 DEG C, and performing aftertreatment, thereby obtaining the SOD type sodalite. The method is free of organic additive, short in synthesis time, convenient in rapid and large-scale production, simple in synthesis step, easily available in raw materials, low in production cost and good in production crystallinity degree.

Description

technical field

[0001] The invention relates to a slow-release and anti-corrosion magnetic nano material and a preparation method thereof, in particular to a preparation technology of composite magnetic nano microspheres. Background technique

[0002] Sodalite is a sodalite cage (SOD or β cage) that belongs to the body-centered cubic arrangement. The space group P-43n has a small pore size and is connected by a single four- or six-membered ring. A SOD cage consists of six Composed of four-membered rings and eight six-membered rings, the pore window of sodalite is only six-membered rings, and the 111-face skeleton structure of sodalite is shown in the attached figure 2 shown.

[0003] Sodalite has important application prospects in adsorption and hydrogen storage, and can also be used as a photochromic material, which has great industrial application prospects. At present, the synthesis of sodalite can be carried out by adding a large amount of organic templates by chemical...
