| 摘 要： | 以浓硝酸处理后的多壁碳纳米管(MWCNTs)为载体,通过微波辅助法简单而快速地制备了高度分散、粒径均一的Pd/MWCNTs催化剂。利用XRD、HRTEM、XPS等手段对催化剂进行了表征。考察了Pd/MWCNTs催化剂对Heck反应的催化活性,并优化了反应温度、碱的种类和用量等反应条件。结果表明,Pd/MWCNTs在Heck反应中具有良好的催化活性。

| Abstract: | Palladium nanocatalysts were highly dispersed on surface-oxidized multi-walled carbon nanotubes (MWCNTs) by the microwave-assisted reduction of PdCl2 solution. These catalysts were characterized by X-ray diffraction, high resolution transmission electron microscopy, X-ray photoelectron spectroscopy. The catalytic properties of the Pd/MWCNTs catalysts for Heck reaction were examined and the conditions such as reaction temperature, kind of base, and dosage of base were optimized. The results indicate that Pd/MWCNTs catalysts present good catalytic activity for Heck reaction. |
