摘要

In the present work, tin incorporated MCM-48 catalysts were prepared by different strategies and applied in the synthesis of MB-AC and MBOH. The performance of the catalysts is strongly affected by mesochannel environment and acid texture. The organic-graft method (Sn-G-MCM-48) can modify the mesochannel environment and enhance the acid intensity and concentration (0.28 mmol/gcat), resulting in the improvement of the catalytic activity to the target reactions. The total yield of MB-AC and MBOH is as much as 68.4% over Sn-G-MCM-48 under mild conditions.
