Abstract A novel method has been developed to synthesize a long-range structured and nanometer-sized mesoporous molecular sieve in reverse microemusion of water in oil. The sizes of the nano-MCM-41 mesoporous silica molecule sieves can be controlled within 20~40nm and no agglomerations occurred even it was calcinated in air at 823K for 4～6h.
