Summary:A precious metal modification method of a titanium silicalite molecular sieve is characterized in that the method comprises the following steps: mixing a titanium silicalite molecular sieve, a precious metal source, and an organic alkali solution, treating the mixture in a closed reaction vessel at 100-200 DEG C for at least 2 hours, taking the product out at normal temperature and normal pressure, drying, and roasting to obtain the precious metal modified titanium silicalite molecular sieve product, wherein the water contained in the reaction vessel can form saturated water steam under the reaction condition, and has a weight ratio to the titanium silicalite molecular sieve being less than 1.2, and the treating capacity of the titanium silicalite molecular sieve is at least 10 g per liter of the reaction vessel volume. The method is low in cost, few in three-wastes, and high in efficiency, and the molecular sieve has good catalytic performance.
