NOVELTY - The preparation method of multi-stage pore mordenite zeolite molecular sieve involves adding sodium hydroxide solution and silicon source to aluminum source, uniformly mixing to obtain an aluminosilicate gel, adding graphene and graphene derivatives to the aluminosilicate gel and then mixing, adding zeolite seed crystal to the mixture, and crystallizing. USE - The method is useful for preparation of multi-stage pore mordenite zeolite molecular sieve (claimed). ADVANTAGE - The method enables simple and economical preparation of multi-stage pore mordenite zeolite molecular sieve with high yield in environmentally-friendly manner. The multi-stage pore mordenite zeolite molecular sieve does not use organic amine structure-directing agent and organic solvent.
