Abstract
The invention relates to a preparation method of a two-dimensional layered-structure material magadiite. The preparation method comprises the following steps of 1, mixing a silicon source, an alkali source and water, wherein according to a mole ratio, the components of the mixture satisfy that SiO2: (NaOH+Na2CO3)=2-8; H2O: (NaOH+Na2CO3)=40-90; and NaOH: Na2CO3=1: 2, 2, putting the mixture into a closed container, and carrying out crystallization at a temperature of 130 to 190 DEG C under self-generated pressure for 6 to 72 hours, and 3, taking out crystallization products, carrying out filtration, carrying out washing until a PH value is in a range of 7-9, and drying at a temperature of 40 to 100 DEG C for 4 to 24 hours to obtain the two-dimensional layered-structure material magadiite. The preparation method has simple processes. The two-dimensional layered-structure material magadiite can be widely used as a catalyst, an adsorbent, a pillar material, an ion exchanger and a nanocomposite material filler.
Description
Technical field
The present invention relates to the preparation method of a kind of two-dimensional layered structure material magadiite.
Background technology
The laminate of two-dimensional layered structure material magadiite is by electronegative SiO
4Tetrahedron forms, preferably chemistry and thermostability are arranged, interlayer have can be exchanged the hydration sodium ion, therefore magadiite has some typical character of layered clay material, for example water and polarity organic molecule that some are little had stronger adsorptive power, has preferably swelling property between the laminate, can hold the little proton that arrives and arrive greatly high-polymer molecular or group, these character have promoted the application of magadiite as aspects such as cationite, sorbent material, pillared composite, catalyzer, nano composite material fillers.
Focus mostly on about the document of two-dimensional layered structure material magadiite at present and be compounded to form coexisting material in one or more of itself and ZSM-5, mordenite, β zeolite, ZSM-35, not yet be seen in report about the preparation of simple phase magadiite.
