Abstract

This invention relates to the field of catalytic material synthesis, and discloses a nano-β molecular sieve, its preparation method and application. The β molecular sieve is synthesized by microwave heating, which, compared with conventional hydrothermal synthesis, has the characteristics of low crystallization temperature, short crystallization time and low water content. The synthesized β molecular sieve has regular crystal morphology, with nano crystals less than or equal to 50 nm, and has a high amount of Brønsted acid and a high Brønsted acid / L-acid ratio.
