摘要:
采用浸渍法制备多孔离子共聚物(PICP)负载的纳米Pd催化剂(Pd/PICP),考察Pd/PICP对苯酚选择性加氢反应的催化性能。通过透射电子显微镜(TEM)、X线衍射仪(XRD)和N2吸附-脱附分析仪等对催化剂进行表征,同时考察催化剂载体、反应溶剂和反应时间对苯酚加氢反应活性的影响。结果表明:Pd/PICP催化剂Pd颗粒粒径为2 nm左右,具有较大的比表面(635 m2/g)和孔体积(1.41 mL/g),在苯酚的还原反应中表现出较高的活性和选择性。在0.1 MPa H2下,n(Pd):n(苯酚)=1:200,反应温度353 K,反应10 h,苯酚的转化率达到99%,环己酮的选择性达到97%,同时催化剂反复使用5次活性几乎没有降低。
Abstract:
The palladium catalyst(Pd/PICP)was prepared by incipient wetness impregnation method with Pd nanoparticles supported on porous ionic copolymer(PICP).The catalytic performances were investigated for the selective hydrogenation of phenol.The Pd nanocatalyst was characterized by transmission electron microscopy(TEM),X-ray diffraction(XRD)and N2 adsorption-desorption analysis, and the reaction conditions,such as the supports,solvents and reaction time were investigated.The Pd/PICP catalyst was highly porous with large specific surface of 635 m2/g,large pore volume of 1.41 mL/g and Pd particle size of about 2 nm.The cyclohexanone was obtained in high yield(97%)with high phenol conversion(99%)under the optimized conditions of 0.1 MPa H2 pressure,with n(Pd):n(phenol)=1:200, at 353 K for 10 h.Moreover,the reusability of the Pd/PICP catalyst was investigated,and the catalyst could be reused at least 5 times without the loss of activity.
