The molecular sieve is prepared in the steps: at the room temperature, hexadecyl trimethyl ammonium bromide is mixed and dissolved with the sodium hydroxide, and is added with TEOS in dropping way, and simultaneously added with Me metal salt water solution and lanthanum nitrate solution in dropping way; the pH value of the mixed solution is adjusted by acetic acid to be 10 to 11, and is mixed for 1 to 2 hours after being stabilized; the sol is moved into a polyfluortetraethylene bottle to be heated and crystallized for 2 days in the oven at the temperature of 100 DEG C; after filtering, washing and drying for nights, and being calcined in a muffle at the temperature of 550 DEG C for 3 to 7 hours, the dual-metal-atom improved MCM-41 mesoporous molecular sieve is obtained.
