| 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.

| Abstract: | 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. |
