The invention belongs to the technical field of molecular sieve and a preparation thereof, and discloses a method for synthesizing a hollow SSZ-13 molecular sieve. The preparation method comprises thefollowing steps: mixing NaOH, a template agent (TMAdaOH) and deionized water, uniformly carrying out mixing, adding an Al source and an Si source to obtain a ZSM-13 molecular sieve synthetic solution, carrying out ultrasonic concussion in an ultrasonic oscillator, adding crystal seeds in the ultrasonic concussion process, transferring the synthetic solution into a reaction kettle for a reaction,washing the solid-phase product with deionized water to be neutral, and carrying out drying and roasting to finally obtain a product which is the hollow SSZ-13 molecular sieve. The preparation methodis simple to operate, a mesoporous template machine is not used, and additional chemical reagents are not added. The synthesized hollow SSZ-13 molecular sieve has a mesoporous structure, has potentialapplication possibility in the fields of gas adsorption and catalysis, and has an important wide application prospect.
