摘要：

In situ formation of the micro- and mesoporous structures MFI and MCM-41 was obtained using a two-template syntheses gel system [C6H13(CH3)(3)NBr and C14H29(CH3)(3)NBr]. The mixed phases were obtained by optimizing template concentrations and reaction temperatures. Constant temperature syntheses as well as sequential high/low or low/high temperature strategies were performed successfully. It was found that the relative amounts of the two structures MFI and MCM-41 in the final products can be controlled by varying the ratio of the templates and by tuning the synthesis temperature. Characterization results indicate that phases of varying complexity were obtained. (C) 1999 Elsevier Science B.V. All rights reserved.
