| 摘 要： | 先将Pd纳米粒子负载于SiO2球表面上,再经包裹、刻蚀、硅烷化修饰,得到氟丙基功能化“蛋黄”型结构催化剂.并采用X射线衍射、透射电镜、N2吸附-脱附和热重等对催化剂进行了表征.结果表明,该催化剂在水相烯烃加氢反应中表现出较高的活性,明显高于未经氟丙基修饰的同类催化剂.该催化剂通过离心便可实现回收,多次循环使用后仍保持较高的活性. |

| Abstract: | Pd nanoparticles were confined in yolk-shell mesoporous silica via encapsulation, etching and modification, producing a functionalized yolk-shell-structured catalyst. This catalyst was characterized using X-ray diffraction analysis, transmission electron microscopy, N2 adsorption-desorption, and thermogravimetric analysis. The catalyst had high activity for olefin hydrogenation in water, higher than that of the unmodified counterpart. The catalyst can be recovered through centrifugation, and its activity is not significantly decreased after several reaction cycles. |
