| 摘 要： | Pd纳米粒子负载的碳纳米纤维是催化Sonogahira偶合反应的良好催化剂,其高长径比使之易于从反应混合物中过滤分离;金属纳米粒子与碳纤维间的强相瓦作用使其具有良好的多次重复使用性.通过电纺丝技术和碳化技术制备了Pd金属纳米粒子负载的电纺碳纳米纤维,透射电镜观察显示最终碳化温度及在该温度下的停留时间是影响钯纳米粒子尺寸及其在纤维中分布的主要因素.并通过所得复合纳米纤维对Sonogahira偶合反应的催化活性研究,发现475～575℃这一温度范围是制备具有良好催化活性的金属钯纳米粒子负载的碳纳米纤维的最佳的碳化温度段. |

| Abstract: | Pd nanoparticles-loaded carbon nanofibers are used as the excellent catalyst for the Sonogahira coupling reaction.Because of their high aspect ratio,such catalysts will be easily separated from the reaction mixture;also,these catalysts have a good reusability due to the firm binding between the carrier and the supported species.In this paper,the Pd nanoparticles-loaded electrospun carbon nanofibers(Pd-NP/CENFs) were made via the electrospinning and carbonization processes.Transmission electron microscope wa... |
