极其细小磨擦非结晶的合金催化剂被化学减小与 KBH4 准备。在在气压的 cinnamaldehyde 的液体阶段加氢期间, Ru-B 催化剂准备了展出优秀选择到 cinnamyl 酒精。当加氢与超声的照耀被执行时,当到 cinnamyl 酒精的选择仍然保持几乎未改变时,反应率能极大地被提高。加氢率随超声的频率或照耀时间的增加被增加。根据各种各样的描述,例如 XRD, XPS, TEM,赌注和 ICP,结构、电子的特征上的超声的照耀的效果磨擦催化剂简短被学习。同时,催化表演上的 ultrasonication 的提升效果也基于 cinnamaldehyde 的选择加氢被讨论到 cinnamyl 酒精。
The ultrafine Ru-B amorphous alloy catalyst was prepared by chemical reduction with KBH4. During liquidphase hydrogenation of cinnamaldehyde at atmospheric pressure, the Ru-B catalyst prepared exhibited excellent selectivity to cinnamyl alcohol. When the hydrogenation was performed with ultrasonic irradiation, the reaction rate could be greatly enhanced while the selectivity to cinnamyl alcohol remained almost unchanged. The hydrogenation rate was increased with the increase of either the ultrasonic frequency or the irradiation time. According to various characterizations, such as XRD, XPS, TEM, BET and ICP, the effect of ultrasonic irradiation on the structural and electronic characteristics of Ru-B catalyst was studied briefly. Meanwhile, the promotion effect of ultrasonication on the catalytic performance was also discussed based on the selective hydrogenation of cinnamaldehyde to cinnamyl alcohol.
