Mesoporous Carbon Supported Pd Catalysts for the Hydrogenation of β-Sitosterol to β-Sitostanol

Supported palladium catalysts on mesoporous carbons (CMC) were prepared by liquid phase reduction and used for the hydrogenation of β-sitosterol to β-sitostanol. Compared to Pd/AC (active carbon), the Pd/CMC catalysts showed significantly higher activity for the hydrogenation of large molecules due to their larger pore size.

摘要采用液相还原法制备了介孔碳 (CMC) 担载的 Pd 催化剂, 用于 β-谷甾醇加氢制备 β-谷甾烷醇反应. 与活性碳担载的 Pd 催化剂相比, Pd/CMC 的活性更高, 这归因于该催化剂具有较大的孔径, 从而有利于较大分子的催化加氢反应.
