Technical field
The present invention relates to two-dimensional layered structure material technology field, be specifically related to the preparation method of a kind of two-dimensional layered structure material kenyaite.
Background technology
Kenyaite is the two-dimensional layered structure material, and its laminate is by electronegative SiO
4Tetrahedron forms, preferably chemistry and thermostability are arranged, kenyaite has some typical character of charged layer structure material, for example water and polarity organic molecule that some are little had stronger adsorptive power, interlayer have can be exchanged the hydration sodium ion, has preferably swelling property between the laminate, can hold and littlely arrive greatly high-polymer molecular or group to proton, these character have promoted kenyaite as the application of the aspects such as the filler of catalyzer, nano composite material, ion-exchanger, sorbent material.
CN 102659166A reported and utilized kenyaite to synthesize the P type zeolite molecular sieve with nucleocapsid structure as crystal seed, but not yet is seen in report about the preparation method of the two-dimensional layered structure material kenyaite of simple phase at present.
