Creation of surface defects on carbon nanofibers by steam treatment被引量：1: 2013年; A direct strategy for the creation of defects on carbon nanofibers (CNFs) has been developed by steam treatment.Nitrogen physisorption,XRD,Raman spectra,SEM and TEM analyses proved the existence of the new defects on CNFs.BET surface area of CNFs after steam treatment was enhanced from 20 to 378 m2/g.Pd catalysts supported on CNFs were also prepared by colloidal deposition method.The different activity of Pd/CNFs catalysts in the partial hydrogenation of phenylacetylene further demonstrated the diverse surfaces of CNFs could be formed by steam treatment.; Zhengfeng ShaoMin PangWei XiaMartin MuhlerChanghai Liang; 关键词：CARBON NANOFIBERS DEFECTS STEAM PALLADIUM

用于Suzuki-Miyaura反应的阴离子交换树脂负载钯催化剂(英文)被引量：3: 2013年; 以碱性阴离子交换树脂Amberlite IRA-900为载体,Pd(C3H5)(C5H5)为金属有机前体,采用金属有机气相沉积法在室温下制备了Pd@IRA-900多相催化材料.紫外-可见光谱分析证明前体和树脂骨架之间的化学作用以及树脂本身的孔道结构使得Pd纳米粒子均匀分散在载体上.透射电镜结果显示钯纳米粒子的平均尺寸为2.6 nm.在较温和的条件下Pd@IRA-900对多种卤代芳烃和苯硼酸的Suzuki偶联都具有良好的催化活性,并且催化剂重复使用5次之后依然具有很好的活性.此外,对树脂载体进行碱性交换处理后可得到一种双功能催化材料Pd@IRA-900(OH),该催化剂在不加入碱的条件下也可以催化碘苯和苯硼酸的Suzuki偶联反应.; 张明明江曼曼梁长海; 关键词：钯阴离子交换树脂 SUZUKI偶联双功能催化剂
