报道了SiO_2负载的聚γ-(组氨酸基)丙基硅氧烷钯催化剂的合成、催化加氢活性及其结构表征.结果表明,标题催化剂对不同底物均有高的催化加氢活性,当N/Pd摩尔比为6.1∶1时,催化丙烯腈的起始加氢速度高达5910 mL H_2/min·mmol Pd.不同溶剂对催化剂的活性有很大影响.
The synthesis, catalytic hydrogenation activity and structural characterization of poly (γ- (histidine) propyl) siloxane supported on SiO_2 were reported.The results showed that the title catalyst exhibited high catalytic hydrogenation activity on different substrates When the N / Pd molar ratio was 6.1:1, the initial hydrogenation rate of acrylonitrile was as high as 5910 mL H 2 / min · mmol Pd. Different solvents had a great influence on the activity of the catalysts.
