摘要：

Direct synthesis of microporous-mesoporous zeolite-beta-SBA-15 (ZBS-15) composite catalyst from the synthetic precursors of SBA-15and zeolite-beta seeds under acidic hydrothermal conditions through the simultaneous self-assembly of mesoporous silica SBA-15 and zeolite-beta has been accomplished and characterized the ZBS-15 catalyst by XRD, N-2 sorption, FT-IR, TPD of ammonia and SEM techniques. The activity of the ZBS-15 composite catalyst for the nitration of benzenes under solvent-free conditions has been investigated, which revealed that there is a significant synergistic influence of both zeolite-beta and SBA-15 materials on the activity of the ZBS-15 catalyst.
