The preparation of highly ordered MCM-41 with extremely low surfactant concentration

Highly ordered pure-silica MCM-41 materials possessing well-defined morphology have been successfully prepared with extremely low surfactant concentration at room temperature. TEM, XRD, and NMR techniques; and synthetic factors (such as pH and amount of water) have been investigated extensively. Experimental results suggested that highly ordered MCM-41 material was formed by a deposition mechanism with silicate rod-like micelles.
