The present invention relates to a hydrocracking catalyst containing a Y-shaped molecular sieve/amorphous silicon-aluminum, and a preparation method thereof. According to the present invention, the carrier of the catalyst comprises a Y-shaped molecular sieve/amorphous silicon-aluminum composite material, the active components of the catalyst comprise at least an element selected from W or Mo, andat least an element selected from Ni or Co, and the assistant active component is P; a surfactant is added during the Y-shaped molecular sieve/amorphous silicon-aluminum composite material preparation process. With the method of the present invention, the Y-shaped molecular sieve, the Y-shaped molecular sieve/amorphous silicon-aluminum composite material and the hydrocracking catalyst can be effectively and conveniently obtained. Compared to the prior art, with the present invention, the process is simplified, the cost is reduced, the selectivity is improved on the basis of the sufficient activity so as to improve the yield of the target product.
