The invention belongs to the technical field of organic synthesis, and discloses a preparation method of a Cu/SiO2 catalyst and an application of the Cu/SiO2 catalyst in preparation of sandalwood 196 through catalytic hydrogenation, the catalyst is prepared by the following steps: adding silicate ester and organic amine into an ethanol solution, uniformly stirring, adjusting the pH value to be alkaline, continuously stirring to obtain a silicon dioxide solution, filtering, washing, and drying to obtain the Cu/SiO2 catalyst. The preparation method comprises the following steps: washing a silicon dioxide solution to be neutral by using deionized water, then dispersing in an ethanol solution, stirring and heating, adding an ammonia water solution of copper salt into the silicon dioxide ethanol solution, continuously stirring and aging, washing to be neutral by using deionized water after aging, and carrying out vacuum drying to obtain the Cu/SiO2 catalyst. The catalyst prepared by the invention realizes the purp
